The characteristics used to distinguish Camurichnus (originally erected as Sagittarius) and its included ichnospecies alternans, have been observed in Bifurculapes laqueatus and therefore Camurichnus alternans is considered a junior subjective synonym of B. laqueatus herein. Hamipes is a distinct ichnogenus that can be differentiated from similar ichnotaxa by the number, shape, and arrangement of the tracks. Cretaceous trackways from Spain that were attributed to Hamipes belong to Bifurculapes. Additionally, the species H. molassicus is moved to the ichnogenus Conopsoides. Since the only other occurrence of Hamipes was the type specimen, the ichnogenus is again known only from the Early Jurassic of Massachusetts, U.S.A. The ichnotaxonomic reassignment, however, extends the geographic and stratigraphic range of Bifurculapes to the Cretaceous of Europe.]]></p></abstract>

Las características usadas para distinguir Camurichnus (originalmente erigido como Sagittarius) y su icnoespecie incluida alternans, han sido observadas en Bifurculapes laqueatus y por lo tanto, Camurichnus alternans es considerado un sinónimo junior subjetivo de B. laqueatus. Hamipes es un icnogénero distinto, que puede ser diferenciado de icnotaxa similares por el número, forma y arreglo de las huellas. Huellas del Cretácico que fueron atribuidas a Hamipes, pertenecen a Bifurculapes. Además, la icnoespecie H. molassicus se traslada al icnogénero Conopsoides. Dado que el único registro alternativo de Hamipes era el ejemplar tipo, el icnogénero de nuevo es conocido sólo por el Jurásico Temprano de Massachusetts, Estados Unidos. Sin embargo, la reasignación icnotaxonómica extiende los rangos geográfico y estratigráfico de Bifurculapes al Cretácico de Europa.]]></p></abstract>
