• Noun:
  • The fossil record shows that the cynodont had features intermediate between reptiles and mammals.
  • Paleontologists study cynodont teeth to understand the evolution of mammalian chewing.

Advanced Usage

• In evolutionary biology: The term "cynodont" is often used to discuss the synapsid lineage leading to mammals.
  • The cynodont's jaw structure provides crucial evidence for the evolution of the mammalian middle ear.

Variants and Related Words
