Rebbachisaurids: Bizarre Lawnmower-Mouthed Sauropods

Please enjoy this episode focusing on the Rebbachisaurids, a family of strange and late-surviving Diplodocoid sauropods that at times developed highly specialized jaws and teeth to aid in low browsing herbivorous diets. https://www.patreon.com/c/DrPolaris Sources used for this video: Bellardini, Flavio; Filippi, Leonardo S.; Carballido, Jose L.; Garrido, Alberto C.; Baiano, Mattia A.
