basilosaurus

Description:

another drawing made during school( and this thing took a long time to do) i used a ball point pen and a permanent marker basilosaurus is a genus of early whale that lived 40 to 34 million years ago in the Late Eocene. it was very elongated archaeocetes , and could of measured in lengths up to 56 ft. Basilosaurus had a wedged-shaped head up to 5 feet long with jaws containing two types of teeth. The teeth in the front, anterior, of the jaw had cone-shaped teeth which caught and held its prey while triangular-shaped teeth in the rear, posterior, of the jaw sliced them up. The type and amount of wear on the teeth of the Basilosaurus indicates that it likely ate fish and squid (Johnston 1991 Carpenter and White 1986)
