3.7" Devonian Lobed-Fin Fish (Osteolepis) Fossil - Scotland
This is a 3.7" long specimen of the Devonian "Lobed-Fin" fish, Osteolepis panderi. It was collected from the Middle Devonian-aged Old Red Sandstone in Caithness, Scotland. It comes with an acrylic display stand.
Osteolepis ('bone scale') is an extinct genus of lobe-finned fish from the Devonian period. It lived in the ancient Lake Orcadie of northeastern Scotland. Osteolepis averaged about 20 centimeters (7.9 inches) long, and was covered with large, square scales. The scales and plates on its head were covered in a thin layer of spongy, bony material called cosmine. This layer contained canals connected to sensory cells deeper in the skin and ended in pores on the surface: they were probably for sensing vibrations in the water.

Osteolepis was a rhipidistian with a number of features in common with tetrapods (land-dwelling vertebrates and their descendants). They were likely close to the base of the tetrapod family tree.
