What is tetrapodomorph?

Tetrapodomorph is a term used to describe a group of extinct fish that are believed to be the ancestors of modern-day vertebrates, including tetrapods (animals with four limbs). They lived during the Devonian period, approximately 416 to 358 million years ago, and are characterized by their paired fins, which resemble the limbs of tetrapods.

Tetrapodomorphs evolved many adaptations that allowed them to navigate shallow waters, such as robust skeletons and muscular fins capable of supporting the weight of the fish on land. Some of the most famous tetrapodomorphs include Tiktaalik and Acanthostega, which are considered to be important transitional forms in the evolution of tetrapods.

The study of tetrapodomorphs has provided important insights into the evolution of vertebrates, including the development of lungs and the transition from fins to limbs. They also played a crucial role in the colonization of land by vertebrates, paving the way for the diverse array of animals that inhabit terrestrial ecosystems today.
