What does baryonyx name mean?

Baryonyx was a fish-eating dinosaur that lived some 125 million years ago. It had long curved claws that it used to help it capture fish. It's name comes from the Greek meaning "heavy claw" and it is the only species in its genus. It's long jaw is low and narrow, and lined with finely serrated teeth - an adaption to aid it in hunting, killing and eating the fish it is though to have preyed on. The 30-foot, 2 ton beast has been found only in England and a couple of areas in Europe. As there are only a limited number of specimens, their size isn't fixed.
