| It would not be safe to assume that the synapsid temporal fenestra is strictly homologous to the lower temporal fenestra of diapsids. |
|
| Here, I have readdressed the oft-noted observation that the size of the dentary increased during the course of synapsid evolution. |
|
| We're not sure if it's from an archaic amphibian, reptile or synapsid, but it gives us hope of finding other tetrapod specimens in the area. |
|
| Accordingly, the role of vertebral rotation in synapsid locomotion might be better investigated in terms of its effect on limb extension and recovery. |
|
| To continue to trace synapsid history after this time, we need to look at the fossil record preserved in younger rocks in South Africa and European Russia. |
|
| The Parareptilia and synapsid amniotes were common during the late Paleozoic, while diapsids became dominant during the Mesozoic. |
|
| One synapsid group, the pelycosaurs, included the largest and fiercest animals of the early Permian. |
|
| We are synapsid tetrapods, a group of reptiles that almost went extinct 200 million years ago in competition with the better-designed dinosaurs. |
|
| Our twenty-first century climax begins more than 300 million years ago when the synapsid separated from the sauropsid lineage. |
|
| Statements that birds are dinosaurs are as silly as claiming that mammals are synapsid reptiles, or that all amniotes are amphibians. |
|
| Ancient synapsids are interesting for many reasons, but we hope our fieldwork this year in Brazil will help to address a particular problem in synapsid evolution. |
|
| During the course of this trip we hope to find new synapsid fossils in a part of the world where they are currently unknown, and to learn more about other animals that were living alongside them. |
|
| The synapsid, early ancestors to mammals, also thrived at this time. |
|
| Archaeothyris was a very early synapsid and the oldest known. |
