with joints, a neck and ribs), but still retained many fish-like traits (e.g. scales, gills, fins). Tiktaalik lived around 375 million years ago during the late Devonian period and was an important transitional species in the evolutionary history of vertebrates, as it represents a link between fish and early tetrapods.
Tiktaalik likely inhabited shallow, freshwater environments and likely used its limb-like fins to navigate through shallow waters and possibly even support itself on land for short periods of time. Its ability to partially support itself on land may have been an important step in the evolution of vertebrates transitioning from aquatic to terrestrial environments.
The discovery of Tiktaalik in Arctic Canada in 2004 provided valuable insights into the evolution of tetrapods and helped scientists better understand the transition from water to land in early vertebrates. This important fossil find has contributed significantly to our understanding of the evolutionary history of vertebrates and the adaptations that allowed them to successfully transition from water to land.
