Eotungidae

Eotungidae is an extinct family of extinct teleost fish that lived during the Cretaceous period. The family is part of the order Eotungiformes, which also includes extinct families like Plethodidae and Pachycormidae. Eotungidae is characterized by its large size and distinctive morphology, including a deep body and a large head with a terminal mouth. The fin arrangement typically includes prominent dorsal and anal fins set far back on the body, and a forked caudal fin.

Fossils of Eotungidae have been found in various locations worldwide, indicating a relatively widespread distribution during the Cretaceous. These fish are often found in marine sedimentary deposits. Their diet is believed to have consisted of smaller fish and invertebrates, based on the jaw structure and tooth morphology observed in fossil specimens. The exact evolutionary relationships of Eotungidae within teleost fish are still a subject of research, but they are generally considered to be an early diverging lineage. The extinction of Eotungidae likely coincided with the Cretaceous-Paleogene extinction event that wiped out many other marine species.
