21. The vertebral transverse processes of mammals are homologous to the cervical ribs of other amniotes . 22. The mesonephros and metanephros of amniotes are derived from different parts of the anamniote opisthonephros. 23. Indeed, many modern day amniotes are dependent on moisture to keep their eggs from desiccating. 24. Biphyletic amphibia and used the name Anthracosauria to describe the labyrinthodont lineage from which amniotes evolved. 25. An "'anapsid "'is an amniote whose skull does not have paraphyletic. 26. Reptiliomorphs are all animals sharing a more recent common ancestry with living amniotes than with living amphibians. 27. Their eggs could survive out of the water, allowing amniotes to branch out into drier environments. 28. From this point the amniotes spread around the globe, eventually to become the dominant land vertebrates. 29. The study of Laurin and Reisz ( 1995 ) was the second major phylogenetic analysis of amniotes . 30. Like many other terrestrial early amniotes , it probably had the diet of insects and smaller animals.
