Sheep ideal research subjects, and thus are not a common model organism. They have, however, played an influential role in some fields of science. In particular, the Roslin Institute of Edinburgh, Scotland used sheep for genetics research that produced groundbreaking results. In 1995, two ewes named Megan and Morag were the first mammals cloned from differentiated cells. A year later, a Finnish Dorset sheep named Dolly, dubbed "the world's most famous sheep" in "Scientific American", was the first mammal to be cloned from an adult somatic cell. Following this, Polly and Molly were the first mammals to be simultaneously cloned and
Saint Bathans mammal It was part of an assemblage of fossils recovered in Saint Bathans in 1978, in what would later be understood to be the Bannockburn Formation (Manuherikia Group), and first described in 2006. Like most small mammal fossils, the Saint Bathans mammal material is rather incomplete, with only a lower jaw fragment and femur being known. The lower jaw is toothless, though the presence of deep tooth sockets suggests that it was toothed in life and that the teeth were lost post-mortem. It bears a long fused mandibular symphysis, an evidently procumbent lower incisor, and five additional sockets that imply a
