Crocodilian
Definition:
(a.) Like, or pertaining to, the crocodile; characteristic of the crocodile.
(n.) One of the Crocodilia.
Example Sentences:

(2) Maximum-parsimony analyses of the total data set of 67 vertebrate alpha A sequences support the monophyletic origin of alligator, tegu, and birds and favor the grouping of crocodilians and birds as surviving sister groups in the subclass Archosauria.
(3) With less than 2 percent of all reptilian species examined, TSD apparently is absent in the tuatara, amphisbaenians and snakes; rare in lizards, frequent in turtles, and ubiquitous in crocodilians.
(4) The mammals examined included 3 eutherian, 2 marsupial and a monotreme species and the reptiles 2 saurian, 1 crocodilian and 1 testudine species.

(7) Molecular evidence for amniote relationships is reviewed, showing that three genes (beta-hemoglobin, myoglobin, and 18S rRNA) unambiguously support a bird-mammal relationship, compared with one gene (histone H2B) that favors a bird-crocodilian clade.
(8) Representative sonagrams of the distress calls of three other species of crocodilians (Caiman crocodilus, Crocodylus niloticus, and Crocodylus siamensis) are presented and compared with sonagrams of alligator distress calls.
