Matching Morphological Features to Fossils
This question requires matching specific morphological terms from Group I to their corresponding fossil groups in Group II. We will analyze the pairings based on the provided correct answer.
Analysis of Fossil Feature Matches
- P: Calices is matched with (2) Gastropod.
- Q: Loph is matched with (3) Conodont.
- R: Sicula is matched with (1) Graptolite. The sicula is the initial, characteristic structure of a graptolite colony.
- S: Calyx is matched with (6) Coral. The calyx (or corallite) is the skeletal cup secreted by a coral polyp.
Correct Matchings
Based on the correct option, the specific matches are:
- P (Calices) → 2 (Gastropod)
- Q (Loph) → 3 (Conodont)
- R (Sicula) → 1 (Graptolite)
- S (Calyx) → 6 (Coral)
This combination corresponds to Option A.
