BGYCT 137 Solved Guess Paper is a 14-question, fully answered revision file for IGNOU's Stratigraphy and Palaeontology course, written for the December 2026 term-end exam. We read five actual question papers from June 2023 to December 2025, tracked which topics keep coming back, and wrote every answer in the same language your IGNOU block uses.
Geology students usually lose marks here in two places: long Indian stratigraphy answers that turn into a mess of formation names, and fossil morphology notes written without the key terms. This file fixes both. Each answer opens with the book definition, lists points in the order examiners check them, and closes with a one-line conclusion.
1. What the BGYCT 137 Solved Guess Paper Covers for Stratigraphy and Palaeontology
BGYCT 137 Stratigraphy and Palaeontology is a School of Sciences geology course in IGNOU's BSCG programme that studies rock layers, Indian stratigraphic successions and the fossil record. This guess paper answers 14 questions across all four blocks, 8 from stratigraphy and 6 from palaeontology.
The split matters. Block 1 and Block 2 carry the principles, classification and Indian rock record, from the Dharwar craton to the Siwalik Group. Block 3 and Block 4 carry fossils, microfossils, horse evolution and the invertebrate groups. Every recent paper draws from both halves, so a file that only covers one side leaves marks on the table.
Each answer is written to a word target that matches its marks and follows a fixed shape: book definition, numbered points, then a short conclusion. If you are preparing more than one course this term, the same format runs across our full range of IGNOU Solved Guess Paper files, so switching subjects does not mean relearning a new layout.
What you will not find is padding. There are no generic "importance of geology" essays and no copied unit summaries. The 14 questions are the ones that past papers point to, and the priority label on each (High or Medium) tells you which to revise first when time runs short.
2. 5 Sample Questions from the BGYCT 137 Solved Guess Paper
Below are 5 of the 14 solved questions, copied exactly as they appear in the file: three 10-mark answers, one 5-mark note and one 5 + 5 pair. The other 9 answers come only with the full PDF.
We picked samples from every block so you can judge the writing on both halves of the course. Read one fully and compare it with your own notes. If the definitions, scholar names and list counts match your IGNOU block, the rest of the file is built the same way.
Stratigraphy and its principles
Question: Define stratigraphy and discuss its various principles in detail.
Meaning of Stratigraphy: "Stratigraphy is a branch of Geology, which deals with the study of rock layers (strata), their sequence and relationship with each other."
The term "Stratigraphy" was coined by the French geologist d'Orbigny in 1849, from the Latin word Stratum and the Greek word Graphia. As it interprets geologic events, it is also called Historical Geology. Nicholas Steno is regarded as the "Father of Stratigraphy", who proposed the law of superposition in 1669.
Basic Principles of Stratigraphy
The book lists eight basic principles (laws) of stratigraphy:
- Order of Superposition: in an undisturbed sedimentary sequence, the lowest bed is oldest and beds become younger upward.
- Original Horizontality: sediments are originally deposited in horizontal layers; tilting or folding occurs later.
- Lateral Continuity: sediments are deposited continuously in all directions up to the limit of the basin until interrupted by erosion.
- Cross-Cutting Relationships: any feature (fault, dyke, valley) that cuts across a sequence is younger than that sequence.
- Inclusions: fragments (inclusions) contained within a rock are older than the rock that encloses them.
- Unconformities: buried surfaces of erosion or non-deposition that represent a break or gap in the stratigraphic record.
- Fossil Succession: fossils occur in a definite, non-repeating order, so strata can be identified and dated by their fossil content.
- Uniformitarianism and Catastrophism: uniformitarianism (Hutton) holds that "present is the key to the past", while catastrophism explains major changes through sudden catastrophic events.
Conclusion: Stratigraphy studies stratified rocks in terms of sequence, composition and age. Its eight guiding principles let geologists reconstruct Earth's history and the evolution of life.
Western and Eastern Dharwar Craton compared
Question: Elaborate the differences between the Western Dharwar Craton and the Eastern Dharwar Craton.
Meaning of Dharwar Craton: "Swami Nath et al. (1976) divided the Dharwar craton into two tectonic blocks, the Western Dharwar Craton (WDC) and the Eastern Dharwar Craton (EDC), separated by the Chitradurga Shear Zone."
| Feature | Western Dharwar Craton (WDC) | Eastern Dharwar Craton (EDC) |
|---|---|---|
| Schist belts | Large belts, volcanics with subordinate sediments | Narrow linear belts with dominant pillowed basalts |
| Basement | Peninsular Gneiss (>3000 Ma) | Dharwar Batholith (2500 to 2700 Ma) |
| Metamorphism | Intermediate pressure (kyanite and sillimanite) | Low pressure (andalusite and sillimanite) |
| Terrain age | Mainly about 3000 Ma terrain | Mainly about 2500 Ma terrain |
Conclusion: WDC preserves older gneissic basement with mature sediments; EDC is a younger, granite-dominated block. The Chitradurga Shear Zone marks the boundary between them.
Gondwana Supergroup: classification, lithology and economic importance
Question: Give an account of the classification, lithology and economic importance of the Gondwana Supergroup.
Meaning of Gondwana Supergroup: "Gondwana Supergroup comprises a thick sequence of fluviatile and lacustrine sediments having a cumulative thickness of about 6 to 7 km with glacial sediments at the base."
The name "Gondwana" was given by H. B. Medlicott in 1872 after the Gond Kingdom of the Narmada region. Edward Suess in 1885 coined "Gondwanaland" for the southern supercontinent. The sequence ranges from the Upper Carboniferous to the Lower Cretaceous and occupies about 50,000 km² in four isolated basins: Koel-Damodar, Son-Mahanadi, Satpura and Pranhita-Godavari.
Classification
Two schemes of classification, both based on lithology and plant fossils, are proposed:
- Two-fold Classification (W. T. Blanford): Lower Gondwana (marked by Glossopteris flora) and Upper Gondwana (marked by Ptilophyllum flora), separated by a slight unconformity at the top of the Panchet Formation.
- Three-fold Classification (O. Feistmantel): Lower Gondwana (Glossopteris flora, warm-humid, coal seams), Middle Gondwana (Dicroidium flora, warm-dry) and Upper Gondwana (Ptilophyllum flora, warm-humid).
Lithology: It is dominantly composed of sandstones and shales with rich coal seams, together with glacial (Talchir) sediments at the base and abundant plant and animal fossils; it is largely a continental sequence with occasional marine incursions.
Economic Importance
- It contains India's major coal reserves in the Lower Gondwana coal seams.
- It hosts fireclay, sandstone and other useful sedimentary deposits.
- Its rich plant fossils (Glossopteris flora) provide strong evidence for continental drift and Gondwanaland.
Conclusion: The Gondwana Supergroup is a thick continental sequence classified into two or three subdivisions on plant fossils. Its coal wealth and Glossopteris flora give it great economic and scientific value.
Fossils, fossilisation and their importance
Question: What are fossils? Discuss the conditions and processes of fossilisation and the importance of fossils in geology.
Meaning of Fossils: "The word 'fossil' is used to refer to the remains or traces of ancient life which have been preserved by natural processes in the sedimentary rocks."
Any organic remains found in rocks older than 10,000 years are termed fossils; younger ones still forming are subfossils. Baron Georges Cuvier (1769 to 1832) is the "Father of Palaeontology".
Conditions for Fossilisation
- Presence of hard parts: shells, bones, teeth and wood resist decay and are preserved.
- Rapid burial: quick covering by sediment cuts off oxygen and protects against scavengers and decay.
- Favourable environment: marine organisms fossilise more easily than land organisms as they are buried rapidly.
Processes of Fossilisation
- Unaltered soft-part (exceptional) preservation: whole organism preserved in amber, tar or ice.
- Unaltered hard-part preservation: shells and bones preserved without change.
- Altered hard-part preservation: permineralisation/petrifaction, replacement, carbonisation, moulds and casts, and tracks and trails.
Importance of Fossils in Geology
- They record the evolution of life and establish ancestor-descendant relationships.
- Index fossils (e.g., trilobites, ammonites) date rocks and aid biostratigraphic correlation.
- They reveal palaeogeography, palaeoclimate and palaeoenvironment of the past.
- They guide the discovery of oil and coal deposits.
Conclusion: Fossils are the only direct evidence of ancient life, formed under strict conditions and varied processes. They are indispensable for dating rocks, correlation and reconstructing Earth's history.
Ammonoid suture patterns and trilobite morphology
Question: Write short notes on: (a) Suture patterns of ammonoids and (b) Morphology and geological history of trilobites.
(a) Suture Patterns of Ammonoids
"In ammonoids the line where a septum meets the outer shell wall is the suture; saddles point towards the aperture and lobes point in the opposite direction."
Three important types of sutures are recognised in ammonoids:
- Goniatitic: rounded saddles and angular (sharp) lobes; found in Late Palaeozoic ammonoids.
- Ceratitic: smooth rounded saddles and finely divided lobes; typical of Triassic forms.
- Ammonitic: complex, finely subdivided saddles and lobes; shown by Jurassic and Cretaceous ammonoids.
(b) Trilobites, Morphology and Geological History
"Trilobites are an extinct group of marine Palaeozoic arthropods; the name means 'three lobes', referring to the trilobation of the skeleton."
Their chitinous exo-skeleton is divided transversely into three parts, cephalon (head, bearing the glabella), thorax (jointed body segments) and pygidium (tail), and longitudinally into a central axial lobe and two pleural lobes. Trilobites first appeared in the Early Cambrian, diversified greatly in the Middle Cambrian and Ordovician, declined through the Silurian to Carboniferous, and became completely extinct at the end of the Permian.
Conclusion: Ammonoid sutures (goniatitic to ceratitic to ammonitic) grow more complex with time; trilobites ruled the early Palaeozoic seas before dying out at the Permian close.

Units 6 and 12 are tracked in the frequency grid rather than written up as full answers in this file. For those two, your textbook or a unit-wise BGYCT 137 Study Material set is the better revision source, and the grid shows you exactly which sub-topics to read.
5. BGYCT 137 Important Questions: Frequency Analysis
Fossils and fossilisation and the Spiti succession are the most repeated BGYCT 137 topics, each asked in all 5 papers from June 2023 to December 2025. Seven more topics, including stratigraphic correlation, microfossils and ammonoid sutures, appeared in 4 of 5.
These are the BGYCT 137 Important Questions that decide most of the paper. The five sessions we tracked are June 2023, December 2023, December 2024, June 2025 and December 2025. You can open any of them yourself on our IGNOU Previous Year Question Paper page and check the counts line by line.
| Topic | Papers asked (of 5) | Sessions seen | Priority |
|---|---|---|---|
| Fossils and fossilisation | 5 | Every session tracked | High |
| Palaeozoic and Triassic of Spiti | 5 | Every session tracked | High |
| Principles of stratigraphy | 4 | All except December 2023 | High |
| Stratigraphic correlation | 4 | All except June 2025 | High |
| Microfossils (types and methods) | 4 | All except December 2025 | High |
| Corals (morphology and history) | 4 | All except December 2025 | High |
| Bivalves and gastropods (history) | 4 | All except June 2023 | High |
| Cephalopods and ammonoid sutures | 4 | All except December 2024 | High |
| Cuddapah and Vindhyan basins | 4 | All except December 2024 | High |
| Dharwar Craton, WDC vs EDC | 3 | June 2023, December 2023, December 2024 | High (due after a gap) |
| Trilobites (morphology and history) | 3 | December 2024, June 2025, December 2025 | High |
| Evolution of horse and climate | 2 | December 2023, June 2025 | Medium |
Two patterns stand out. Palaeontology topics from Blocks 3 and 4 fill seven of the twelve rows above, so they deserve at least half your revision time. And topics that skipped the latest paper, like the Dharwar craton and microfossils, are the ones we flag as due, because in this five-paper window most core topics came back within one or two sessions.
6. BGYCT 137 Exam Pattern and Answer-Writing Plan
The BGYCT 137 term-end exam is 2 hours for 50 marks, and all four questions are compulsory: 5 very short answers (5×2), 4 short notes (4×5), one 10-mark long answer with an OR choice, and one two-part 5+5 question with an OR choice.
The December 2023 official IGNOU question paper gave 9 very short options (answer any 5) and 7 short-note options (answer any 4). That choice is your safety net: prepare the High-priority topics well and you will almost always find enough questions you can answer fully.
| Question | Format | Marks | Word target | Suggested time |
|---|---|---|---|---|
| Q1 | Any 5 very short answers from about 9 | 5×2 = 10 | 40 to 50 words each | 15 minutes |
| Q2 | Any 4 short notes from about 7 | 4×5 = 20 | About 150 words each | 45 minutes |
| Q3 | One long answer, internal OR | 10 | About 450 words | 25 minutes |
| Q4 | Two linked parts, internal OR | 2×5 = 10 | About 150 words per part | 25 minutes |
That plan leaves around 10 minutes for diagrams and a read-through. Diagrams are not decoration in this paper: the question paper itself asks for well-labelled figures, so a quick sketch of a trilobite, a brachiopod valve or a suture line is worth practising alongside the written answers.
7. BGYCL 138 Practical File Index for BGYCT 137 Students
BGYCT 137 has a companion lab course, BGYCL 138 Stratigraphy and Palaeontology: Laboratory, with 8 experiments: five on fossil groups and three on maps and stratigraphic columns. Each one expects labelled line drawings in your practical file.
The guess paper is for the theory exam, but the lab and theory share the same fossils and maps, so your practical file doubles as diagram practice. Use this index to check that your file has every experiment and the right drawings before the lab counselling session.
| Exp. | Experiment | What goes in your file | Theory link |
|---|---|---|---|
| 1 | Brachiopods: morphology, systematic position and age | Labelled valves, strophic vs astrophic hinge line, costae and plicae | Unit 13 |
| 2 | Bivalves: morphology, systematic position and age | Interior of left valve, cardinal teeth, lunule and escutcheon | Unit 14 |
| 3 | Nautiloids and ammonoids: morphology, systematic position and age | Septa, septal necks, simple nautiloid vs complex ammonoid sutures | Unit 15 |
| 4 | Trilobites: morphology, systematic position and age | Glabella, facial suture, free and fixed cheeks, cranidium | Unit 16 |
| 5 | Echinoids: morphology, systematic position and age | Regular vs irregular forms, ambulacral plates, apical system | Unit 16 |
| 6 | Preparation of physiographic map of India | Divisions marked on a blank outline map with key basins | Unit 3 |
| 7 | Preparation of lithostratigraphic map of India | Main stratigraphic units plotted and their spread described | Block 2 |
| 8 | Preparation of stratigraphic columns | Columns of rock successions, bedding contacts, basin correlation | Units 1 and 2 |
8. Who Should Use the BGYCT 137 Guess Paper
This file is for IGNOU students taking BGYCT 137 in the Bachelor of Science (General) BSCG programme or the Bachelor of Science (Multidisciplinary, FYUP) BSCM programme, who want to revise the most repeated questions before the term-end exam.
It works best if you have already read the blocks once and now need a tight, exam-shaped revision set. If you are sitting a backlog paper, working full-time, or starting late in the term, the High-priority tags give you a clear order to work in. Students in the multidisciplinary stream can also browse the wider BSCM guess Paper range for their other courses this term.
It is not a substitute for the textbook. If you have not opened the blocks at all, start with the units, then use these answers to practise writing. That is how most of our students pass a subject heavy on names and dates like this one.

10. FAQs on the BGYCT 137 Guess Paper
Quick answers to what BGYCT 137 students ask us most on WhatsApp: what the file contains, which papers were analysed, the exam pattern, BSCM use, the practical course and how to order.
What is the BGYCT 137 Solved Guess Paper for Stratigraphy and Palaeontology?
It is a 14-page PDF with 14 fully answered questions for IGNOU's BGYCT 137 Stratigraphy and Palaeontology course. We built it by analysing five past term-end papers from June 2023 to December 2025. Each answer follows the IGNOU block wording, opens with the textbook definition and matches its word target to the marks, so you can revise and write in the exam style.
How many questions are in the BGYCT 137 Stratigraphy and Palaeontology guess paper?
The file has 14 solved questions: six 10-mark long answers, five 5-mark short notes and three paired 5 + 5 notes. This page shows 5 of them in full, which are Q1, Q5, Q7, Q9 and Q14. The remaining 9 answers, covering topics such as Spiti, Deccan Traps, microfossils and horse evolution, come only with the complete PDF.
Which past papers were used for BGYCT 137 important questions?
We tracked five IGNOU term-end papers: June 2023, December 2023, December 2024, June 2025 and December 2025. Every topic was counted across these papers, and each question carries a High or Medium priority label. Fossils and fossilisation and the Spiti succession appeared in all five papers, while seven more topics appeared in four, which is why they top your revision list.
What is the exam pattern for BGYCT 137 Stratigraphy and Palaeontology?
The term-end exam runs for 2 hours and carries 50 marks, with all four questions compulsory. Question 1 asks any five very short answers for 10 marks, Question 2 asks any four short notes for 20 marks, Question 3 is one 10-mark long answer with an OR choice, and Question 4 has two 5-mark parts with an OR choice.
Is the BGYCT 137 guess paper useful for BSCM students?
Yes. The file follows the BGYCT 137 course content, not a particular programme, so it suits students taking this course in the Bachelor of Science (General) BSCG programme and in the Bachelor of Science (Multidisciplinary) BSCM programme under the four-year structure. As long as your hall ticket shows BGYCT 137, the syllabus, blocks and exam pattern covered here apply to you.
Does the BGYCT 137 guess paper cover the BGYCL 138 practical?
No, the guess paper is written for the BGYCT 137 theory exam. The lab course BGYCL 138 has eight experiments on brachiopods, bivalves, cephalopods, trilobites, echinoids, the physiographic map, the lithostratigraphic map and stratigraphic columns. This page lists all eight in a practical file index so you can check your lab file, and the fossil answers help with drawing practice too.
How do I order the BGYCT 137 Stratigraphy and Palaeontology guess paper?
Send a WhatsApp message to 9899436384 mentioning BGYCT 137 and your exam session. Our team will reply with the price and payment details. Once your payment is confirmed, the complete 14-page PDF is sent to you on WhatsApp. You can message the same number later if you have a doubt about any answer while revising.
Can the BGYCT 137 guess paper replace the IGNOU textbook?
No, and we would not advise using it that way. The guess paper covers the 14 questions that past papers point to most strongly, but the exam can still ask short 2-mark items from any unit. Read the blocks at least once, then use these answers to practise structured writing and to revise the high-priority topics in the final weeks.
11. Who Prepared the BGYCT 137 Answers
The answers were prepared by Prateek Talwar and reviewed by Sheetal Kirola at Unnati Educations, Vikaspuri, Delhi, working from the IGNOU BGYCT 137 blocks and five past term-end papers.
Prateek Talwar wrote and structured the 14 answers, matching each definition, scholar name and list count to the IGNOU block text.
Sheetal Kirola reviewed the file for accuracy against the course material and checked the question frequency claims against the five papers.
