Description
Olivia Vanhaesebroucke, Olivier Larouche, and Richard Cloutier track body shape diversity in early lobe-finned fish in this 2025 paper. These fish, the group that later gave rise to land vertebrates, changed greatly across the Devonian and Carboniferous periods. Mass extinctions and shifting environments punctuate that span.
The team measured shape from landmarks on reconstructions of the body, cheek, and skull roof. Shape diversity rose in the Middle Devonian, as first forests spread and reefs peaked. Skull and cheek diversity fell at the end-Devonian extinction, then recovered later as reefs returned and survivor groups rose. Shared ancestry drove much of the skull pattern, the authors find.
