Maekawaevva

Maekawaevva is a genus of extinct ray-finned fish that lived during the Early Cretaceous period. Fossil remains of Maekawaevva have been discovered in Japan, specifically within the Kuwajima Formation. This geological formation is known for its well-preserved freshwater fish fossils, providing valuable insights into the aquatic ecosystems of that time.

The genus Maekawaevva is characterized by several distinctive anatomical features, particularly in its skull and fin structures. These characteristics have allowed paleontologists to classify it as a distinct group within the teleost fishes. The size of Maekawaevva specimens suggests they were relatively small to medium-sized fish, likely inhabiting rivers and lakes.

Research into Maekawaevva contributes to our understanding of early teleost evolution and the biodiversity of Cretaceous freshwater environments in East Asia. The specific adaptations observed in its skeletal structure may indicate its ecological niche and feeding habits. Further study of its fossils continues to refine our knowledge of prehistoric fish life.
