«Our limited understanding of the incredible jaws of these arachnids, together with terminology that is unstandardized and even contradictory, has hindered our ability to classify them and figure out where they fit in the arachnid tree of life because, much like the cranial anatomy of vertebrates, the jaws of solifuges contain most of the relevant information,» said Lorenzo Prendini, a curator in the Museum's Division of Invertebrate Zoology and an author on the paper.
