Tessellated calcified cartilage (TCC) is a hallmark of the chondrichthyan skeleton, yet its development early in ontogeny across the four major groups (batoids, galeomorphs, squalomorphs, and holoceph...

Dipnoans (lungfishes) reached their peak of taxonomic diversity and morphological disparity during the Devonian Period, followed by a pronounced decline in both thereafter. The Late Devonian (Famen...

New findings from articulated head and trunk material of Megamastax amblyodus yield previously unseen morphological details of a Silurian stem osteichthyan.

A tiny, articulated, near-complete osteichthyan from the early Silurian Chongqing Lagerstätte, represents the oldest osteichthyan occurrence including microfossils, and the earliest articulated remain...
