Canis latrans, coyote brain endocast Oviraptor Later CretaceousThis is a brain endocast of the a coyote. An endocast or endocranial cast is a cast made of the mold formed by the impression the brain makes on the inside of the neurocranium (braincase), providing a replica of the brain with most of the details of its outer surface.
