The fossil record of birds in the Mesozoic of Gondwana is mostly based on isolated and often poorly preserved specimens, none of which has preserved details on feather anatomy. We provide the description of a fossil bird represented by a skeleton with feathers from the Early Cretaceous of Gondwana (NE Brazil). The specimen sheds light on the homology and 3D structure of the rachis-dominated fea...

The fossil records of Kateretidae from the Mesozoic are significant for understanding origin and early evolution family. recent discoveries Cretaceous kateretids have provided valuable information about palaeodiversity morphological disparity taxa. Here, we establish a new genus species kateretid beetles, Scaporetes rectus gen. et sp. nov., based on specimen preserved in mid-Cretaceous Kachin a...
