The Permotriassic branchiosaurid Tungussogyrinus Efremov, 1939 (Temnospondyli, Dissorophoidea) from Siberia restudied [PDF]

open access: yesFossil Record, 2009
The enigmatic temnospondyl amphibian Tungussogyrinus bergi Efremov, 1939 shares clear synapomorphies with other branchiosaurids indicated by an anteriorly elongated infratemporal fossa and small branchial denticles.

Climatic drivers of latitudinal variation in Late Triassic tetrapod diversity

open access: yesPalaeontology, Volume 64, Issue 1, Page 101-117, January 2021., 2021
Abstract The latitudinal biodiversity gradient (LBG), the increase in biodiversity from the poles to the equator, is one of the most widely recognized global macroecological patterns, yet its deep time evolution and drivers remain uncertain. The Late Triassic (237–201 Ma), a critical interval for the early evolution and radiation of modern tetrapod ...

GEOMETRIC MORPHOMETRICS OF THE SKULL ROOF OF STEREOSPONDYLS (AMPHIBIA: TEMNOSPONDYLI) [PDF]

open access: yesPalaeontology, 2006
Abstract:  Geometric morphometric analysis using relative warps is applied to the skull roof of 62 species of stereospondyls and their closest outgroups (i.e. basal archegosauriforms) from among temnospondyl amphibians. Twenty‐one landmarks and five taxonomic groups are used for comparisons.
