Deinosuchus is an extinct genus of alligatoroid crocodilian related to the modern alligator that lived 82 to 73 million years ago (Ma), during the late Cretaceous period. The name translates as "terrible crocodile" and is derived from the Greek deinos (δεινός), "terrible", and soukhos (σοῦχος), "crocodile". The first remains were discovered in North Carolina in the 1850s; the genus was named and described in 1909. Additional fragments were discovered in the 1940s and were later incorporated into an influential, though inaccurate, skull reconstruction at the American Museum of Natural History. Knowledge of Deinosuchus remains incomplete, but better cranial material found in recent years has expanded scientific understanding of this massive predator.

Astreptorhachis is an extinct genus of Late Carboniferous dissorophoid temnospondyl within the family Dissorophidae. It is known only from one species, Astreptorhachis ohioensis, that was collected from Jefferson County, Ohio by the Ohio Geological Survey in 1953 and described by Peter Vaughn in 1971. The holotype and only known specimen consists of a few neural spines and is currently reposited in the Smithsonian Museum of Natural History. The genus name derives from the Greek words astreptos ("inflexible") and rhachis ("backbone"). The specimen was recognized as being similar to the dissorophid Platyhystrix rugosus from the southwestern United States in have greatly elongate neural spines. Astreptorhachis is differentiated from Platyhystrix by the fusion of successive neural spines and the extensively developed tubercles that cover the external surfaces. It is speculated that the elongation of the spines served to stiffen the backbone, being advantageous for terrestrial locomotion, but the purpose of the fusion of successive spines remained unclear in the absence of other material of this taxon.
