Jack Wilkin is a palaeontologist and graduate researcher at the Camborne School of Mines, University of Exeter, in the United Kingdom. His research focuses on the isotopic geochemistry of macrofossils, principally belemnites, from the Middle Jurassic of southern Germany for paleoclimate studies. Before starting his Masters in CSM, he completed his BSc (Hons) in palaeontology from the University of Portsmouth in 2017 where he did his dissertation on fish taphonomy. His research interests include isotopic geochemistry, the south German Jurassic, theropod palaeobiology, and taphonomy of fossil Lagerstätten. Jack also works as a teaching assistant.

The Morrison Formation is renowned worldwide as one of the world’s most significant locations for dinosaur fossils. It covers more than 150 million square kilometres, running from Alberta in Canada to New Mexico in the United States, and from Idaho across to Nebraska (Fig. 1). The Morrison dates to the Oxfordian stage of the late Jurassic period, some 155 million to 148 million years ago. It is what is known as a Konzentrat-Lagerstätten, meaning that it has a very high concentration of fossil remains, with extensive bone beds created by flash floods depositing lots of bones in one place. The Morrison provides palaeontologists with remarkable insight into a late Jurassic terrestrial ecosystem. Not only does the formation contain some of the largest din
