Tetrapods across the Permo-Triassic

“The decline in species richness from the equator to the poles is referred to as the latitudinal diversity gradient (LDG). …Terrestrial and marine tetrapod spatial biodiversity patterns were studied using a database of global tetrapod occurrences. Reconstructed terrestrial LDGs contrast strongly with the generally unimodal gradients of today, potentially reflecting high global temperatures and prevailing Pangaean super-monsoonal climate system during the Permo-Triassic.” Excited about the PT tetrapods?
