| 21. | According to John George Wood in " The Illustrated Natural History ( Mammalia ) " ( 1853 ):

| 22. | *Reevaluation of several taxa of Chinese lagomorphs ( Mammalia : Lagomorpha ) described on the basis of pelage phenotype variation
|
| 23. | Around the end of the Triassic period, a Therapsid developed traits or characters that are diagnostic of the class Mammalia.
|
| 24. | For such a genus to be monophyletic, it would have to include both the class Mammalia and the class Aves.
|
| 25. | On the other hand, the vasa recta are formed by efferent arterioles exiting the glomeruli of mammalia-type nephrons.
|
| 26. | This wider group includes some families that trait-based taxonomy does not include in Mammalia, in particular Tritylodontidae and Brasilodontidae.
|
| 27. | He very early contributed to the Zoologist and various Scottish magazines, and ultimately became an acknowledged authority on mammalia and birds.
|
| 28. | Later authors found it to be neither a dryolestoid nor a docodont, and found it to be of uncertain placement within Mammalia.
|
| 29. | He is distinguished for his researches on fossil mammalia, and for the support which his studies have rendered to the theory of evolution.
|
| 30. | Pan-Mammalia consists of all mammals and their fossil ancestors back to the phylogenetic split from the remaining amniotes ( the Sauropsida ).
