#FossilFriday it’s been a great week visiting the Texas vertebrate paleontology collection and the Texas Science museum to study proboscideans! From left to right below: the holotype of Gnathabelodon (Blancotherium) buckneri, a Torynobelodon mandible, and a Cuvieronius skull.

Holotype partial cranium of Gnathabelodon (Blancotherium) buckneri. A white skull on a green-gray plaster slab with long upward curving tusks and a long tuskless mandible. Top front view of the jaw of a shovel-tusked elephant relative. The mandible is beige with huge procumbent lower incisors set in a massive flaring symphysis.Partially reconstructed skull of the short-jawed gomphothere Cuvieronius. The skull is beige with flaring upper tusk alveoli and a wide narial opening

New in @science.org ...since our first discoveries of early tetrapods, they have been thought of as "amphibians" characterized by aquatic larvae. But is this true? For the first time, we report exceptional fossils of stem tetrapod babies that upend this paradigm. 1/n www.science.org/doi/10.1126/...

Direct development of stem tetrapods across the fin-to-limb transition

Modern amphibians are characterized by an aquatic larval stage that ends abruptly with a period of widespread tissue remodeling (metamorphosis) upon transition to terrestrial adulthood. A transient la...

For those interested in the tradition of geological Gesamtkunstwerk in natural history museums, check out Stefanie Jovanovic-Kruspel's recent article: shttps://valuepast.hypotheses.org/6678. Not sure I'd actually noticed the pterodactyls on the columns of the @sedgwickmuseum.bsky.social.

Building Deep Time – Museum Architecture in Oxford, Vienna & Cambridge

Stefanie Jovanovic-Kruspel shows us natural history museum buildings which make deep time visible in stone and space.
