Osteolepiform Fish Fossil

(Osteolepiform Fish Fossil)
Osteolepiform Fish Fossil

The Osteolepiform fish are thought to be the ancestors of the Tetrapoda due to their paired lobed fins being homologous to the limbs, and the choanae (posterior nostril). Osteolepis possessed two rounded dorsal fins placed posteriorly, and a heterocercal tail with a larger lower lobe. They have thick rhombic scales covered with a cosmine layer (hence the shine). Here is a unique opportunity to obtain an example of this ancient group of fish thought to have given rise to the Tetrapod bauplan. This wonderful example is preserved in dorsolateral aspect and shows all the classic the features with incredible detail. There are two repaired cracks which are quite unobtrusive. Note too the very fine finnage seen here. This one was professionally prepared in the United Kingdom. I was fortunate to secure a group of specimens collected during the 1980s. With the Cruaday Quarry no longer in operation, and declared a Site of Special Scientific Interest there will be little forthcoming in the future. Please ask for shipping quote when purchasing.
