Caudal vertebrae, the vertebrae that make up the tail of tailed animals
A series of spurs "tail" out to the north, hence the name "Caudal".
According to a study by Kevin Padian there are eight cervical vertebrae, fourteen dorsals, four or five sacrals and up to 38 caudal vertebrae.
The interspinous membrane of the first dorsal fin, the individual soft rays and the caudal fin are also spotted, with the caudal fin heavily spotted.
The fossil is one of the few known crocodyliform caudal vertebrae and comes from the Kem Kem Beds that have produced the fossils of very large predatory dinosaur species: Spinosaurus, Carcharodontosaurus and Deltadromeus.
Graziano and colleagues suggested an alternative principle of organization for the primary motor cortex and the caudal part of the premotor cortex, all regions that project directly to the spinal cord and that were included in the Penfield and Woolsey definition of M1.
SHH signaling from the MDO induces a posterior-to-anterior wave of expression the proneural gene Neurogenin1 in the major (caudal) part of the thalamus, and Ascl1 (formerly Mash1) in the remaining narrow stripe of rostral thalamic cells immediately adjacent to the MDO, and in the prethalamus.
