Per E. Ahlberg, a professor of evolutionary biology at Uppsala University in Sweden reported in Nature that limbs, not fins were attached to Ventastega; this inference is based on the anatomy of key parts of its pelvis and its shoulders. The fossils reported were found on the Kurzeme/Courland Peninsula in what is now western Latvia. They are 365 million years old. A skull, shoulders, and part of the pelvis of Ventastega curonica were found. They indicate it was more tetrapod than fish and looked similar to a small alligator. The discovery contributes to the understanding of the evolutionary transition from fish to tetrapods (animals with four limbs, whose descendents include amphibians, reptiles, dinosaurs and birds, and mammals).
