A Triassic crown squamate

open access: yesScience Advances, 2022
Mammals, birds, and squamates (lizards, snakes, and relatives) are key living vertebrates, and thus understanding their evolution underpins important questions in biodiversity science. Whereas the origins of mammals and birds are relatively well understood, the roots of squamates have been obscure.

open access: yesDanmarks Geologiske Undersøgelse Serie B, 1982
Deposition during the Triassic continued in the basinal areas developed during the Permian, but in Early Triassic the highs were also gradually covered by sediments. The pattern of sedimentation in the two mega-basins is analogous to that of the Rotliegendes, i.e. with a pronounced, more coarse-grained elastic infill in the northern basin (fig.
