Shark tooth collagen stable isotopes (δ15N and δ13C) as ecological proxies

The isotopic composition of tooth‐bound collagen has long been used to reconstruct dietary patterns of animals in extant and palaeoecological systems. For sharks that replace teeth rapidly in a conveyor‐like system, stable isotopes of tooth collagen (δ13CTeeth & δ15NTeeth) are poorly understood...
