300 million-year-old tail print shows that scales evolved earlier than expected arstechnica.com/science/2024/0

A diadectid skin impression and its implications for the evolutionary origin of epidermal scales royalsocietypublishing.org/doi

"the epidermal scales in #diadectids and other terrestrial #tetrapods prevented the evaporation of water from their bodies, which may have helped them survive the #desert climate that prevailed on #Pangea during the #Permian"

A new stem-tetrapod fish from the Middle–Late Devonian of central Australia tandfonline.com/doi/full/10.10

"#Tetrapodomorpha comprises the limbed tetrapods and their closest fish relatives.. The group diversified greatly in both marine and freshwater habitats during the Middle-to-Late #Devonian while giving rise to several distinct lineages, including the earliest limbed #tetrapods."

Who were the first proponents of the water-to-land transition of vertebrates? Did the idea that tetrapods originate from fish precede the discovery of transition fossils? Were the discussions on land-to-water (e.g. ichthyosaurs origin) and water-to-land transitions contemporary?
I’m trying to place some late 18th/early 19th century science writing into context, but have no background in the history of science.

#Fossil bone #histology reveals ancient origins for rapid juvenile growth in tetrapods nature.com/articles/s42003-022

Early #tetrapods like #whatcheeriads were related to modern #reptiles, #amphibians and #mammals but were in a different evolutionary lineage than the ancestor of those three groups. To find rapid growth in as old an animal as #Whatcheeria was really unexpected.

Cracking open a fossil bone reveals rapid juvenile growth in early tetrapods

It was long thought that these early animals (ancestors of #amphibians, #reptiles, #birds, and #mammals) grew very slowly throughout their lifetime, gradually getting bigger and bigger, similar to a modern #salamander... #Whatcheeria's elevated growth rates as a juvenile shows us that maybe slow and steady growth is not actually the ancestral condition for all #tetrapods.
