Lungfish diversity in Romer's Gap: Reaction to the end-Devonian extinction [PDF]
, 2016 Romer’s Gap, the interval following the end-Devonian extinction event, has been described as a post extinction trough for vertebrates. It is a time roughly equivalent to the Tournaisian stage of the early Carboniferous, and has been characterized by a ...

Journal of Comparative Neurology, Volume 532, Issue 3, March 2024.After stimulation of the statoacoustic nerve (N. VIII) or of vocalization‐relevant forebrain structures of the Chinese fire‐bellied toad Bombina orientalis, we discovered increased durations of activation of motor nerve root recordings of isolated male brains in comparison to female brains. These increased durations in male brains can be interpreted as

Journal of Morphology, Volume 285, Issue 1, January 2024.The Australian lungfish, Neoceratodus forsteri, is the earliest branching species of extant lungfishes having changed little over the last 100 million years and is thought to be a key species for the fish–tetrapod transition. This ultrastructural study of the cornea reveals it is not split into dermal and scleral components and is similar to that of ...
