Flesh-Ripping Dinosaurs Replaced Their Teeth Multiple Times a Year

by Riley Black/Smithsonian.com

For carnivorous dinosaurs, staying sharp was of the utmost importance. Whether they were slicing flesh from the flanks of their prey or crushing the bones of their victims into splinters, the business of eating other animals can be tough on the teeth.

Like all toothy dinosaurs, prehistoric carnivores replaced their teeth throughout their lives. New cutlery constantly grew in their jaws to push old or broken teeth out of the way. And a new study published today in PLOS ONE reveals how often three Mesozoic meat eaters replaced their chompers. The evidence that these carnivores grew new teeth several times a year also can tell us new things about how these animals hunted and fed.

The research, published by Adelphi University paleontologist Michael D’Emic and colleagues, continues previous work that examined the teeth of herbivorous dinosaurs. In 2013 D’Emic and coauthors calculated that the long-necked Jurassic herbivores Camarasaurus and Diplodocus replaced one tooth every 62 days and 35 days, respectively. Plant food can be abrasive, wearing down teeth quickly, and so herbivorous dinosaurs required a constantly renewed supply. But what about the carnivores?

  1. Ms Carol, to answer your question, I have a simple answer to you, if you have followed my comments in some of your previous articles. Again, I refer you to the works of Zecharia Stichin, who translated to the best of his abilities and understanding of the customs and the meaning of words in Ancient times, and the Sumerians telling us that we were genetically engineered by the Annunaki, in Akkadian meaning “the fifty who from heaven came down to Earth”, a similar meaning for the hebrew word: Nephilim. The Annunaki made us, the ADAMU, later Humans, males and females at their image but at lower/weaker version of them. Their aim was to build a slave and I told the rest of the story. In addition to not having replaced teeth or long longevity as the dinosaurs, we also have 4000+ genetic defects, weaker bones than apes, no night vision like all apes… So, in the end they were making a slave, a GMO and who cared about the well being and how perfectly he/she was build. They can make as much as they wanted and we were expandable in their eyes… This is why we were so badly designed, along with domesticated plants and animals. That cannot be found in Nature. Period!
