Tzaganosuchus

Tzaganosuchus is an extinct genus of fossil crocodile from the Gobi Desert of southern/southeastern Mongolia. The type and only known species for this genus, Tzaganosuchus infansis was discovered during a joint paleontological expedition conducted by the Soviet Union and Mongolia. That same expedition also described several other reptiles including several species of "Shamosuchus" and the archosauromorph genus "Irenosaurus" (originally named "Tchoiria egloni"). The prefix of the name "Tzaganosuchus" is a Mongol word derived from the locality where its fossils were first found: the Tsagan Khushu Quarry, which dates to the Paleogene epoch (Thanetian stratigraphic stage) and is part of the Naran-Bulak Formation. The suffix "suchus" is a Latin word for crocodile.
Taxonomy.
When it was described in 1983, along with a number of other reptile species, "Tzaganosuchus" was put in the subfamily Crocodylinae, which contains the genus "Crocodylus" and virtually all extant crocodile species and is the largest the three Crocodylidae subfamilies.
Description.
Based purely on its taxonomic location, it is clear that "Tzaganosuchus" is closely related to many modern crocodile species, such as the Nile Crocodile, as well as several fossil species that have only recently (from the standpoint of geologic time) become extinct, such as "Rimasuchus" or "Voay". Therefore, "Tzaganosuchus" must retain several traits common to these groups, such as the long, pointed snout, amphibious lifestyle, and so on.
Distribution and habitat.
"Tzanganosuchus" lived in the Gobi during the Paleocene–Eocene Thermal Maximum, a time of increased temperature and humidity worldwide, that was most extreme during the last stages of the Paleocene. The time in which this crocodile lived also corresponds closely to the Gashatan age of Asian land mammals, which "Tzangosuchus" may have preyed upon.
