A MIDDLE JURASSIC LABYRINTHODONT |
| |
| Abstract: | A member of the labyrinthodont came from Lower Shaximiao Formation (middleJurassic) was discovered in Dashanpu Quarry, Zigong, Sichuan Basin, China. The materials included a complete skull, a fragmental mandible and several vertebrae. Many factors suggest that the specimen is a brachyopid labyrinthodont. The teeth are labyrinthine in cross-section. The skull and mandible are ornamented. The skull is short and broad, absent tabular horns and refers to Braehyopidae. |
