arcuatetikkaus
Arcuatetikkaus is a genus of extinct ray-finned fish that lived during the Early Cretaceous period. Fossils of Arcuatetikkaus have been discovered in what is now Europe. The genus is characterized by its distinctive body shape, which is described as being laterally compressed and somewhat elongated, with a prominent arch in its dorsal profile, hence the genus name "arcuatus" meaning arched. Its caudal fin is typically forked.
The teeth of Arcuatetikkaus are small and pointed, suggesting a diet of small invertebrates or possibly other
