Tello Obelisk is a vertical, rectangular shaft with a step-like notch at the top. The obelisk is carved in relief on all four sides and consists of two representations of a single-type creature. The head, body and tail occupy one or the other broad sides, while the legs, genitalia and other subsidiary elements occupy the narrow sides. These creatures have been interpreted as a "cat-dragon" type of creature (by Tello) and as a cayman (by Rowe and Lathrop). The large artifact may portray a creation myth.
