Acantholipan is a genus of herbivorous nodosaurid dinosaur from Mexico from the early Santonian age of the Late Cretaceous. It includes one species, Acantholipan gonzalezi.[1]
Discovery and naming
In the north of Mexico, fragmentary fossils have been found of nodosaurids. A partial skeleton excavated at Los Primos near San Miguel in Coahuila, was described in 2011. When Rivera-Sylva and colleagues reported the discovery of this specimen, CPC 272, they initially considered it too fragmentary to name.[2] Later it was judged that the remains were sufficiently distinct to be given a binomial name.
In 2018, the type species Acantholipan gonzalezi was named by Héctor Eduardo Rivera-Sylva, Eberhard Frey, Wolfgang Stinnesbeck, Gerardo Carbot-Chanona, Iván Erick Sanchez-Uribe and José Rubén Guzmán-Gutiárrez. The generic name combines a Greek akanthos, "spine", with lipan, the usual Spanish designation of the Lápai-Ndé, the "Gray People", a tribe of the Apache inhabiting the area of the find. The specific name honours the Mexican paleontologist Arturo Homero González-González, the chairman of the Museo del Desierto at Saltillo. Acantholipan is the first ankylosaurian species named from Mexico.[1]
The holotype specimen, CPC 272, was found in a marine layer of the Pen Formation and dates from the Santonian. It consists of partial skeleton lacking the skull. Its remains include a back vertebra, a tail vertebra, a piece of a rib, the underside of the left humerus, an upper left ulna, the underside of the left femur and an osteoderm of the posterior thorax.[3] The fossil is part of the Colección Paleontológica de Coahuila, Museo del Desierto, Saltillo.[1]
