Nothing soothes the savage breast like a crappy dinosaur toy! No? Yeah! Pretty sure this old boy was supposed to be an eraser. Had a lavender one like this as a kid...mad by Russ. I know they made several varieties. I'm almost positive this "species" is just some fake, made up dinosaur. I always loved the sculpt on this guy...the blunt head, the spines goin' down his back, the armored belly...just neat-o-rific!
