The yoshisaurus is a strange dinosaur vaguely resembling a raptor of some sort, devoid of feathers and scales which are small. It's body is bulbous and smooth, appearing almost like a frog, and like a frog it possesses a long sticky tongue capable of lashing out in the blink of an eye. Intelligent for dinosaurs, they possess a simple languages of grunts and other noises. They are shy creatures, easily spooked, but if befriended they may be trained as a mount and will remain brave, so long as their rider is about.
