We performed a baraminological analysis on nineteen fossil equid species using a morphological dataset obtained from the published literature. From a baraminic distance correlation analysis, we found evidence that all nineteen species belong to a single monobaramin. The 3D ANOPA distribution revealed a linear trajectory of equid species with sixteen species in the main axis and three species in a side-branch. The order of species in the ANOPA trajectory closely corresponds to the order of stratigraphic appearance, indicating that the fossil equids form a true stratomorphic series. We interpret the strata as post-Flood, concluding that the equid fossil record evidences a rapid, post-Flood, intrabaraminic diversification.
