Etymology
The specific name spielbergi refers to American film director Steven Spielberg, whose film Jurassic Park the authors considered to have contributed to the revival of interest in the earth's ancient past.[1]
Description
At 55 mm (2.2 inches) in total length, Protognathinus is one of the largest known fossil beetles in the superfamily Scarabaeoidea. It is comparable to other large fossil beetles such as Cheirotonus otai and Oryctoantiquus borealis.[2] Like other beetle fossils known from the Messel Pit, Protognathinus fossils retain the color of the exoskeleton.[1]
The details of the classification within the family are not well understood, and it is sometimes placed in Lampriminae and sometimes in Lucaninae. Morphological similarities with early Cretaceous species Litholamprima qizhihaoi, described from the Yixian Formation, have been pointed out.[3]
