täpploendeid

Täpploendeid is a genus of extinct lampreys found in the Baltic Sea region of Europe. They lived during the Early Miocene, around 20-25 million years ago. Fossil evidence of the Täpploendeid species has been discovered in the Baltic region, specifically in Sweden and Denmark.

The name Täpploendeid is derived from the Swedish word "täpploende," which means "dawn" or "break of day." This name is thought to refer to the fact that the fossil remains of these lampreys were first found in a light-colored, dawn-like sedimentary rock.

The Täpploendeid lampreys were characterized by their relatively small size, typically ranging from 20-30 centimeters in length. They exhibited a smooth, cycloid scales, which gave their bodies a streamlined appearance. The fossil evidence also suggests that they had a relatively short, broad snout and a small dental shield.

The Täpploendeid genus is often compared to the living sea lamprey (Petromyzon marinus), which is also found in the Baltic region. However, unlike the sea lamprey, the Täpploendeid species lacked the characteristic parasitic feeding behavior of their living relatives. Instead, it is believed that the Täpploendeid lampreys were opportunistic feeders, using a combination of suction and grasping to capture prey.

Further research on the Täpploendeid species has provided valuable insights into the evolution and biology of lampreys in the Miocene era.
