An Illinois scientist says he's discovered prehistoric remains belonging to a reptile thought to be the onetime "lizard-eating ruler of the sea."  The "Tribune" says Field Museum scientist Jim Holstein uncovered the fossil remains of the so-called "T-Rex of the Sea" while on a trek through the Nevada mountains.  

The 28-foot-long reptile considered to be a "super predator" died roughly 245-million-years ago.  Scientists believe the remains are of the earliest type of ichthyosaur - that's the Greek word for "fish lizard" - which experts say closely resembled a dolphin and evolved from being a land animal to a sea animal.
