Durlstotherium is an extinct genus of mammal from the Early Cretaceous. It contains a single species, Durlstotherium newmani. The type specimen was found in Durlston Bay, Dorset, after which the genus was named.[1] D. newmani was named after a British pub landlord, Charlie Newman.[2] Durlstotherium and two of its contemporaries, Tribactonodon and Durlstodon, had tribosphenidan (three-cusped) molars, which are an advanced characteristic among eutherian mammals and suggest that the group emerged earlier than the Early Cretaceous.[1]
