What is a hybodontiform shark?
- This newly identified species, which has been named Durnonovariaodus maiseyi, was a type of hybodontiform shark that lived around 150 million years ago during the Jurassic Period. The extinct hybodontiforms are the closest relatives to today's sharks.
What is heterodont condition in Port Jackson shark?
- Except mammals heterodont condition is found in Port Jackson Shark (Heterodontus), in several reptiles, specially among mammal-like reptiles. B. According to the Mode of Attachment of Teeth: This type of dentition is the rule among mammals. In this condition, the teeth are lodged in bony sockets or alveoli of the jaw bone (Fig. 2.32).
Where was the tooth whorl from the fossil shark Helicoprion?
- The tooth whorl from the fossil shark Helicoprion was at the tip of the lower jaw. The older teeth are at the center of the whorl, which is about 20 cm (7.8 in) in diameter.
Are megatooth sharks related to Otodus obliquus?
- However, in 1987, shark expert H. Cappetta recognized the C. auriculatus - C. megalodon lineage and placed all related megatooth sharks along with this species in the genus Carcharocles. The complete Otodus obliquus to C. megalodon transition then became clear and has since gained the acceptance of many other experts with the passage of time.
