Dinosaur of the day Stenopelix, a small (likely) ceratopsian that we only know from impressions in sandstone slabs.

Interview with Michele Hollow, an award-winning journalist, and author of the book “Jurassic Girl: The Adventures of Mary Anning, Paleontologist and the First Female Fossil Hunter”, a historical fiction book for both young and less young readers.

In dinosaur news this week:

  • The most complete and oldest known pachycephalosaur was discovered and named Zavacephale rinpoche
  • There’s a new "thunder dome" pachycephalosaur, Brontotholus harmoni
  • There’s a new flat-headed hadrosaur, Ahshislesaurus wimani, that was as large as a T. rex
  • There’s a new hadrosaur dinosaur from Morocco named Taleta taleta (yes the genus and species name are the same)
