The dinosaur of the day: Hanssuesia

  • Pachycephalosaurid that lived within the Late Cretaceous in what’s now Alberta (Dinosaur Park Formation, Dinosaur Provincial Park, Oldman Formation) and Montana (Judith River Formation)
  • Appeared much like Pachycephalosaurus, walked on two legs, had brief arms, lengthy tail, had a dome on high of the cranium
  • Estimated to be 7.9 ft (2.4 m) lengthy
  • Sort species is Hanssuesia sternbergi
  • Named based mostly on a cranium dome
  • Had a thick cranium roof, like different pachycephalosaurs
  • Had distinctive options, together with the entrance of the dome was as vast within the entrance because it was within the again
  • Initially named Troodon sternbergi by Barnum Brown and Erich Schlaiker in 1943
  • Discovered the holotype to symbolize a virtually absolutely grownup particular person
  • Species title is in honor of Charles M. Sternberg, who discovered the fossil in 1928 in southern Alberta
  • Within the 1943 description, Brown and Schlaikjer wrote it was “A slightly massive species”
  • In 1945, Charles M. Sternberg referred Troodon sternbergi to Stegoceras sternbergi
  • Additionally has been referred to Gravitholus previously
  • Named by Robert Sullivan in 2003
  • Genus title is in honor of paleontologist Hans-Dieter Sues for his work on pachycephalosaurs
  • Sullivan talked about that Stegoceras had, maybe unintentionally, develop into a “wastebasket taxon” for small to medium sized pachycephalosaurs present in North America
  • Word: Sullivan in the identical paper the place he named Hanssuesia additionally synonymized Ornatotholus with Stegoceras (so he each lumped and cut up)
  • Sullivan wrote: “Brown and Schlaikjer (1943) have been largely right of their characterization and evaluation of this taxon, and it’s to their credit score that the species is herein resurrected” (but it surely was exhausting to characterize till extra specimens have been discovered)
  • Brown and Schlaikjer thought that there was particular person variation, adjustments in progress, and variations in gender, inside Stegoceras (therefore the variations within the people discovered)
  • Six referred specimens, along with the holotype, which might be largely frontoparietals (entrance of the cranium)
  • Nonetheless some debate in regards to the validity of Hanssuesia
  • Ryan Schott and David Evans had beforehand argued that Hanssuesia was Stegoceras, and that the variations within the dome have been as a consequence of ontogeny (modified because it grew)
  • In 2020, an summary by Aaron D. Dyer, and Mark J. Powers within the Canadian Society of Vertebrate Paleontology urged Gravitholus and Hanssuesia to be synonymous with Stegoceras

Enjoyable Truth:
