'A completely different story': 300 million-year-old fossils reveal the first vertebrate land dwellers weren't what we thought, researchers claim
New 300-million-year-old baby fossils of crocodile-like predators are challenging long-held theories on how vertebrates first transitioned to land.

The brief
Researchers claim that newly analyzed fossils indicate the first vertebrate land dwellers may not have been amphibian-like. The discovery involves fossilized babies of ancient crocodile-like predators, including one specimen previously mislabeled as a 'baby lamprey' from a 66-year collection by a Vietnam Veteran.
Coverage from Smithsonian Magazine, Live Science, and Phys.org emphasizes that these findings uproot textbook assumptions and rewrite evolutionary theory. Other reports from Popular Science, The Economic Times, and 404 Media describe the discovery as turning major theories upside down.
Future attention will focus on how these findings change the understanding of animal adaptation to land, as coverage suggests the history of land life is being rewritten.
