 | Transparent thin sections prepared from fossilized bone material often yield clues about the anatomy and physiology of now-extinct dinosaurs and other creatures. |
| The micrograph below illustrates minerals that have formed in the fossilized bone from an ancient species of pleurodira. |
| The second group, the suborder Pleurodira only has two families, the side-necked and snake-necked turtles. |

| High-speed film analyses (250 frames/sec) of feeding in the semiaquatic freshwater turtle Pelusios adansonii (Pleurodira) demonstrate, that prey (turtles were fed fishes and snails) is captured by a combination of suction and ram-feeding. |
| Aquatic feeding is the primitive mode of prey capture in vertebrates and is therefore of special interest in the study of vertebrate evolution. |
| The ultrastructure of the dorsal lingual epithelium of the semi-aquatic West African mud turtle, Pelusios castaneus, is described. |
