__TOC__
==History==
''Bauhcis moranii'' is an extinct species of [dicotyledonous](/source/dicotyledonous) fossil flowering plant in the family Fabaceae and subfamily [Caesalpinioideae](/source/Caesalpinioideae), native to central Mexico. This species was described in 2002 from two leaf impressions found in the Coatzingo Formation, an Oligocene geological formation located near Tepexi de Rodríguez ([Puebla](/source/Puebla)).<ref name="Calvillo-Canadell-2002" />

Morphological studies, confirmed by [principal component analysis](/source/principal_component_analysis) (PCA), as well as a cladistic study using the Hennig86 program, show that this fossil can be confidently classified within the tribe [Cercideae](/source/Cercideae) and that it occupies an intermediate position between the genus Cercis and certain species of the genus Bauhinia.<ref name="Calvillo-Canadell-2002" />

== Etymology ==
The generic name, "''Bauhcis''," is a combination of the generic names ''[Bauhinia](/source/Bauhinia)'' and ''[Cercis](/source/Cercis)'', indicating that the leaf characteristics of these two genera are found in a mosaic form in the fossil material.<ref name="Calvillo-Canadell-2002" />The specific epithet, "''moranii''," is a tribute to Dante Jaime Morán-Zenteno, director (1994-2002) of the Institute of Geology in [Mexico City](/source/Mexico_City), for his unconditional support of [paleobotany](/source/paleobotany).<ref name="Calvillo-Canadell-2002" />
