Say hello to: TYLOSAURUS

TYLOSAURUS (TY-lo-sawr-us) "Knot Lizard" (Greek tylos = knot or knob + sauros = lizard. The reason for this name is not known.)

Not a DINOSAUR, but one of the largest known of the MOSASAURS. This seagoing lizard lived in the NIOBRARA SEA during the late CRETACEOUS PERIOD. It was 20 to 40 feet (6 to 12m) long and had a long, slim body. It had huge jaws; sharp, cone-like teeth; and flipper-like hands and feet. It was a savage hunter and ate fish and shellfish. Tylosaurus FOSSILS have been found in Kansas.
