It is possible that dinosaurs roamed the northern hemisphere millions of years before was previously believed.

Image
  by  University of Wisconsin-Madison More  than  200  million  years  ago,  dinosaurs  first  appeared  on  Earth.  How  and  when  did  they  spread? When  faced  with  fractured  fossil  records,  paleontologists  have  been  debating  that  subject  for  decades. According  to  the  conventional  wisdom,  reptiles  first  appeared  on  the  southern  half  of  the  ancient  supercontinent  Pangea,  known  as  Gondwana,  millions  of  years  ago.  Later,  they  spread  to  the  northern  half,  known  as  Laurasia. With  evidence  indicating  the  reptiles  were  prevalent  in  the  northern  hemisphe...

The oldest tadpole discovered by Argentinean scientists dates back to the dinosaur era.

BUENOS AIRES: The oldest known tadpole, the larval stage of a giant frog species that coexisted with dinosaurs approximately 161 million years ago during the Jurassic Period, has been found by scientists in Argentina to have exceptionally preserved fossil remnants. The 16-centimeter-long fossil, according to the researchers, provides insight into the evolution of frogs and toads by demonstrating how little tadpoles have altered from their Jurassic ancestors. Although no older tadpole fossils have been discovered, the oldest known frog fossils are significantly older. The researchers claim that the specimen, which is from a previously identified species named Notobatrachus degiustoi, is so well preserved that it has remnants of various soft tissues that are often absent from fossils. For example, the fossil preserves the tadpole's eyes and nerves as black impressions in their anatomical positions. The fossil was discovered in 2020 while searching for dinosaur bones on a ranch in the...
