QUESTION 11
Based on rock type, which paleoenvironment did Pseudoatrypa devonica live in?
clean, clear water, fast-moving currents or waves, and hard, sandy substrates.
Oturbid water, little current activity, and soft, muddy substrates.
QUESTION 12
Pseudoatrypa
devonica
Spinatrypa
spinosa
Tropidoleptus
carinatus
Why would a larger, more rounded shell develop in the lineage of this brachiopod?
