Ancient Australian air-breathing fish from 380 million years ago

Science Daily - Paleontology - Tue, 02/06/2024 - 14:14
The rivers of Australia, which once flowed across its now dry interior, used to host a range of bizarre animals -- including a sleek predatory lobe-finned fish with large fangs and bony scales. The newly described fossil fish discovered in remote fossil fields west of Alice Springs has been named Harajicadectes zhumini by palaeontologists.

Rare 3D fossils show that some early trees had forms unlike any you've ever seen

Science Daily - Paleontology - Fri, 02/02/2024 - 10:47
In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. In a new study, researchers describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.
