Teeth and Ornithomimids
Few ornithomimids have teeth and Pelecanimimus is the most renowned of all the toothed mimics. The dinosaur was originally presented in a short Letter to Nature as unique and multi-toothed Spanish dinosaur. The holotype consists of the anterior portion of a skeleton including the skull and all of the cervical vertebrae. This holotype is preserved on a slab that has been shown in the description paper under induced fluorescence. The fossil is accompanied by a hypothetical illustration of the animal. This recreation and the description of the original material are discussed in subsequent studies such as Allain, et al. 2014 which describes a number of European ornithomimosaurs. Prior to this, however, Pelecanimimus was scrutinized and praised for possessing mineralized skin and muscle in the fossil matrix. This discovery was described by Briggs, et al. 1997 which determined the validity of the materials and the presence of skin impressions in the slab in addition to the mineralized material attached to the skeleton itself.
