R. beckerorum is the second proterochampsid species described from the Pinheiros-Chiniquá Sequence.
Researchers have described a brand new species of proterochampsid archosauriform, a crocodile-like animal that will have crammed an ecological area of interest like that of contemporary day crocodilians. They regarded much like crocodiles and lived in the course of the center and late Triassic in what’s now South America. This explicit species, Retymaijychampsa beckerorum was present in Southern Brazil and lived in the course of the Center-Higher Triassic interval.
Retymaijychampsa beckerorum lived about 237 million years in the past and had a crocodile-like cranium and dermal armor. The brand new species was described from a single, almost full hindlimb that was excavated from the “Linha Várzea 2 (Becker) Web site, situated within the municipality of Paraíso do Sul, Rio Grande do Sul, Brazil.”
In keeping with the paper describing the brand new species, R. beckerorum is the second proterochampsid species described from the Pinheiros-Chiniquá Sequence. The Pinheiros-Chiniquá Sequence is the oldest sedimentary rock formation that makes up the Santa Maria Formation in Brazil. Thus far, it’s thought of to be the one of many oldest members of the Archosauromorpha clade. The researchers say that Retymaijychampsa beckerorum partially fills what known as a ghost lineage from the Center Triassic to the early Late Triassic. A ghost lineage describes an ancestor that will or could not have persevered. There is no such thing as a fossil proof of the ancestor however can nonetheless be believed to have existed on account of gaps within the fossil document, or on account of genomic proof.

The paper describing Retymaijychampsa beckerorum, “A brand new proterochampsid archosauriform from the Center–Higher Triassic of Southern Brazil” could be learn on the Acta Palaeontologica Polonica web site.
