Eotyrannus

Eotyrannus (meaning "dawn tyrant") is a genus of tyrannosauroid theropod dinosaur hailing from the Early Cretaceous Wessex Formation beds, included in Wealden Group, located in the southwest coast of the Isle of Wight, United Kingdom. The remains (MIWG1997.550), consisting of assorted skull, axial skeleton and appendicular skeleton elements, from a juvenile or subadult, found in a plant debris clay bed, were described by Hutt et al. in early 2001. The etymology of the generic name refers to the animal's classification as an early tyrannosaur or "tyrant lizard", while the specific name honors the discoverer of the fossil. The exact location of the discovery of the holotype specimen has not been revealed due to its importance and the possibility of new material to be collected as the coastline recedes. From what is mentioned in the description, the specimen was found on the southwestern coast of the Isle of Wight, between Atherfield Point and Hanover Point. In 1995, local collector Gavin Leng brought a claw he had found along the coastline to Steve Hutt who worked at the old Museum of Isle of Wight Geology at Sandown. Gavin Leng revealed the location of where the claw was discovered, and over the next few weeks the site was carefully excavated, and the fossils removed in a hard matrix. Over the next few years the specimen was carefully researched with scientists from the University of Portsmouth, and with help from the Natural History Museum. Eventually in 2001, Eotyrannus was given its name along with its specific epithet in honour of Mr. Leng. The material was described briefly in 2001 by Hutt et al. In July 2018 Darren Naish, a colleague of Hutt who helped produce the preliminary description, created a GoFundMe fundraiser in order to release a monograph of the specimen, which received well over its goal. The monograph was eventually published in the journal PeerJ in 2022. A number of characters present in the holotypic specimen are unique to the genus.
