The holotype of a species does not cease to be a holotype when the nominative
species is synonymized. Sereno proposes that the two species, *C. yandica* and
*S. santensis,* are the same species, so the holotype of *C. yandica* is (while
remaining a holotype) is a referred specimen of *S. santensis.* I think *C.
caudatus* was considered a juvenile of *C. yandica,* else otherwise it's a
nomen dubium (as is *C. yandica*) and not considered a equivalent species.

Little steps are often the hardest to take. We are too used to making leaps
in the face of adversity, that a simple skip is so hard to do. We should all
learn to walk soft, walk small, see the world around us rather than zoom by it.
