摘要:
) Mass Extinction 66 million years ago (Ma), using microfossils (isolated teeth) preserved in a South Pacific sediment core spanning 72-43 Ma. Our record does not sh

摘要:
t subterranean rodents that use their incisors to dig (chisel-tooth digging) have a constrained cranial shape which is probably driven by a necessity to create high

摘要:
Quantifying regulatory gene effects on dental morphology and function has implications for the underlying mechanisms that generated dental diversity
Data from: Controlled feeding experiments with diets of different abrasiveness reveal slow development of mesowear signal in goats (Capra aegagrus hircus)

摘要:
Dental mesowear is applied as a proxy to determine the general diet of mammalian herbivores based on tooth-cusp shape and occlusal relief. Low, blunt

doi:10.5061/dryad.6f052
摘要:
surface of the teeth are modified with wear, making difficult the identification of many isolated fossil teeth. We use geometric morphometrics to te
