Which one of the following best describes ‘Sidersaura marae&rsqu...
Paleontologists in Argentina recently found fossil fragments of a new species of dinosaur named Sidersaura marae.
About Sidersaura marae:
  • It is a new species of sauropod dinosaur.
  • It lived during the Cenomanian age of the Late Cretaceous epoch, between 96 and 93 million years ago, in today’s Patagonian region.
  • It belongs to the Rebbachisauridae, a large family of sauropod dinosaurs known from fragmentary fossil remains from South America, Africa, North America, Europe, and Asia.
  • These dinosaurs are distinguished from other sauropods by their distinctive teeth.  Some species had tooth batteries similar to those of hadrosaurs and ceratopsian dinosaurs.
  • Rebbachisaurids were very important dinosaurs in Cretaceous ecosystems and disappeared in the middle of this period in an extinction event that took place 90 million years ago.
  • It is one of the last rebbachisaurids.
  • Features of Sidersaura marae:
  • It was up to 20 m in length, had an estimated mass of 15 tons, and had a very long tail.
  • One of the characteristics that distinguishes Sidersaura marae from other dinosaurs is the star-shaped shape of the hemal arches (tail bones).
  • Its skull bones are robust, unlike those of the rest of its closest relatives.
  • Another cranial feature that differentiates Sidersaura marae from other rebbachisaurids is its frontoparietal foramen, which is basically a hole in the roof of the skull.
Hence option c is the correct answer.
