Terrestrisuchus gracilis

Terrestrisuchus gracilis

Terrestrisuchus gracilis sprinted on exceptionally long, slender limbs through the ancient island scrublands of Late Triassic Britain, pursuing prey entirely on dry land. Its delicate skull housed sharp, serrated teeth specialized for snapping up insects and small reptiles with speed and precision. Abundant fossil skeletons preserved inside limestone fissures provide an exceptional look at a cursorial lifestyle far removed from modern semi-aquatic crocodilians.
