The Nigersaurus is a 500-toothed dinosaur that has a bizarre vacuum-cleaner like mouth. The dinosaur is known as the lawn mower or fern mower because it likely mowed down the ferns of Africa in its day. The dinosaurs tooth replacement ability is also incredible.
The researchers also found that Nigersaurus had 500 teeth, with up to eight replacements stacked up behind each tooth. The 50 columns of teeth, lined tightly along a squared-off jaw, made the dinosaur’s mouth essentially a foot-long (0.3-meter) pair of scissors.
“Among dinosaurs, Nigersaurus sets the Guinness record for tooth replacement,” study lead author Paul Sereno, a paleontologist at the University of Chicago said in a statement.
