Dolichorhynchops is an aquatic reptile having a large head and short neck. The studies reveal that the Dolichorhynchops is not a good biter and chewer of the cretaceous seas. The Dolichorhynchops mainly resides on the soft bodied squids rather than the fish available in the water. As it is not a good biter it takes soft bodied squids as its major food source.

These exhibits strong and conspicuously developed articulating surfaces for muscle attachments. The humerus is like femur and exhibits strong and developed articulating surfaces for muscle attachments.

The Dolichorhynchops are about 10- 17 feet long. And it is believed that these lived in the shores of North America . These Dolichorhynchops mainly depend on the soft bodied squids. These are characterized by having a large neck, snout is narrow and the teeth are small.
