"Lathamoserpens had a relatively thick wall with presumed lamellar construction. All Lathamoserpens specimens have evenly spaced curves, and with one exception there are always two curves at nearly equivalent points from the ends of the shell....These observations imply thatLathamoserpens represents a mineralized shell, and that sinuous shape reflects its shape in life, not taphonomic distortion of a flexible organism."
