zalambdodont การใช้
- Both genera have zalambdodont ( V-shaped crests ) and transversely elongated with the paracone and metacone ( cusp ) appressed or connated.
- The zalambdodont molars appear to link it to notoryctid marsupial moles, but detailed study of the teeth of these two groups suggests that they have evolved independently, and " Yalkaparidon " is anatomically otherwise very different from the marsupial moles.
- These specimens of " Yalkaparidon " exhibit a melange of characters : the molars are zalambdodont ( a distinctive tooth type also found in the marsupial mole " Notoryctes ", the living placental'insectivores "'Solenodon ", tenrecs and golden moles, as well as a number of fossil groups ); the incisors are very large and hypselodont ( open-rooted and hence ever-growing, similar to those of rodents ); the basicranial region of the only known skull is very primitive, somewhat similar to those of plesiomorphic bandicoots.
