du Bus 1872 described Priscodelphinus cristatus based on partial and poorly preserved skulls with extremely long and narrow rostra with a huge number of densely packed teeth. He estimated the rostrum of a large specimen to be 90 cm (35 in) long and the cranium to be 20 cm (7.9 in) long and slightly wider. He also found a series of well-preserved cervicals and a few of the anterior-most thoracics.[3]
Kellogg 1925 described Eurhindelphis bossi based on an almost complete skull missing ear bones, both mandibles, sixteen vertebrae, ten ribs, an incomplete scapula, a humerus, and a partial sternum. Kellogg named his species after its discoverer, Norman H. Boss, who had discovered the type specimen in 1918.[4] Kellogg also described several other fossils.
Lambert 2005 recombined these two taxa and placed them under the generic name Xiphiacetus.[5]
