Species– †obliquus (and more)
Status: EXTINCT. Cobelodus lived from the middle to the late Carboniferous period.
Average Size and Length: Based on fossil records Cobelodus was about 6.6 feet long.
Head: It had a very round head, with big bulbous eyes.
Demographic, Distribution, Habitat, Environment and Range: Cobelodus lived in North America in today what is Iowa and Illinois. Because of its eyes, research suggests Cobelodus lived and hunted in very deep depths.
Diet: Cobelodus most likely hunted squid and crustaceans.
Aesthetic Identification: Although it was related to chimaeras, it was very different from the appearance of the modern sharks. It had a high-arched back, and a dorsal fin placed far to the rear, above the pelvic fins. Cobelodus had 12-inch long, flexible cartilaginous ‘tentacles’ sprouting from its pectoral fins.
Speed: Research suggests Cobelodus was probably a cruiser at the dep depths of the bottom. Its body was not built for speed.
