Abstract: We describe a partial vertebral column of a mosasaur identified as cf. Tylosaurus sp. from the lower Niobrara interval of the Mancos Shale south of Galisteo in Santa Fe County, New Mexico. Invertebrate fossils collected from the same horizon include the inoceramids cf. Inoceramus (Cremnoceramus) deformis and cf. Inoceramus (Platyceramus ) platinus and dense growths of the oyster Pseudoperna congesta. They suggest a Coniacian age. This is the oldest documented mosasaur from New Mexico.
