Tracks of a crocodyliform are known since Cretaceous, at least. Tracks representing the ichnofamily Batrachopodidae are described from the Early Cretaceous (late Aptian ) Calonda Formation ( Angola ) by Mateus et al. (2017), who name a new ichnotaxon Angolaichnus adamanticus .
Crocodilia (/ k r ɒ k ə ˈ d ɪ l i ə /) is an order of semiaquatic, predatory reptiles that are known as crocodilians.They first appeared during the Late Cretaceous and are the closest living relatives of birds.
The world was largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic groups present in modern times can be ultimately traced back to origins in the Cretaceous.
Stolokrosuchus is an extinct genus of crocodyliforms that lived during the Early Cretaceous. Its fossils, including a skull with a long thin snout and bony knobs on the prefrontal, have been found in Niger. Stolokrosuchus was described in 2000 by Hans Larsson and Boubacar Gado. The type species is S. lapparenti.
Modern crocodilians, a subgroup of Neosuchia, emerged during the Late Cretaceous. [8] Crocodylomorph diversity was severely reduced by the end-Cretaceous extinction event . [ 9 ] The last group of terrestrially adapted crocodylomorphs was the Sebecidae , a group of large predatory notosuchians which persisted in South America until the middle ...
Sarcosuchus (/ ˌ s ɑːr k oʊ ˈ s uː k ə s /; lit. ' flesh crocodile ') is an extinct genus of crocodyliform and distant relative of living crocodilians that lived during the Early Cretaceous, from the late Hauterivian to the early Albian, 133 to 112 million years ago of what is now Africa and South America.
Notosuchia is a suborder of primarily Gondwanan mesoeucrocodylian crocodylomorphs that lived during the Jurassic and Cretaceous.Some phylogenies recover Sebecosuchia as a clade within Notosuchia, others as a sister group (see below); if Sebecosuchia is included within Notosuchia its existence is pushed into the Middle Miocene, about 11 million years ago.
