| Abstract: | Exceptional new material of the enigmatic Late Jurassic / Early Cretaceous reptile Monjurosuchus has been recovered from the non marine Yixian Formation,western Liaoning,China.The discovery provides compelling evidence for the resolution of a long standing mystery as to its relationships:this animal is a primitive member of Choristodera,a clade of distinctive aquatic reptiles.Further,the exquisite preservation of unique integumentary structures offers a rare glimpse of the external morphology of an extinct Mesozoic reptile. Monjurosuchus had webbed feet and was at least partially aquatic.The mode of preservation,in a fine tuffaceous shale,implies almost simultaneous death and burial,when a mass of volcanic ash smothered the lake in which the reptiles lived. |
