Using zinc isotopes, researchers investigated the diet of #megalodon - the largest #shark to have ever lived - & reasons for its extinction. New paper in Nature Communications by Jeremy McCormack (MPI-EVA Leipzig, Goethe-Universität) et al. See: bit.ly/3wVQWSl & nature.com/articles/s4146…

Really excited to finally share our research on zinc isotopes and the diet of ancient #sharks including #megalodon. Michael Griffiths @SoraLKim @pederzani_sarah @BourgonNicolas Klervia Jaouen and many more nature.com/articles/s4146…

In our new paper we show how to gain an additional dietary proxy from the during collagen extraction commonly discarded dissolved mineral phase of skeletal material. Helen Fewlass @BourgonNicolas Virginie Sinet-Mathiot @geoffreymsmith Jean-Jacques Hublin and more link.springer.com/article/10.100…

We have a new paper out in PNASNews today utilizing phosphate oxygen and clumped isotopes to infer endothermy in extinct megatooth shark, Otodus megalodon. @SoraLKim @ClumpedIsotopes Robin B. Trayler Jeremy McCormack Alliya Akhtar William Paterson University pnas.org/doi/10.1073/pn…

New findings from #Ilsenhöhle cave in #Ranis show: Modern humans reached NW Europe more than 45,000 years ago & were the makers of the Lincombian-Ranisian-Jerzmanowician (LRJ) technocomplex. New studies in nature & NatureEcoEvo. nature.com/articles/s4158… & tinyurl.com/3ksm2586

In our new paper, we investigate diet-tissue and tissue-tissue zinc isotope fractionation in gilt-head seabreams and discuss the implications for ecological studies using this new dietary proxy. Klervia Jaouen @BourgonNicolas Théo Tacail and more. link.springer.com/article/10.100…
