On this episode, we talk about:

  • The dinosaur of the day: Pentaceratops aquilonius
  • Pentaceratops lived 75 million years in the past
  • The species was found in 2014, after its fossils had been gathering mud in a Canadian museum for over 75 years
  • Dr. Nick Longrich, from the College of Tub in England, realized it was a brand new species when he studied them
  • He noticed that Pentaceratops, together with a second dinosaur, Kosmoceratops, was extra much like dinosaurs from the American Southwest
  • Initially Pentaceratops was categorized as Anchiceratops and the second dinosaur as Chasmosaurus
  • Penteceratops aquilonius was extra like a primitive model of Pentaceratops sternbergii (found in 1921) from New Mexico
  • There are numerous totally different sorts of Chasmosaurinae (massive, horned dinosaurs with frills), in all probability as a result of dinosaurs unfold out all around the continent after which tailored and advanced into new species. Competitors between these teams would have stored them from shifting after (between north and south)
  • That is why scientists have discovered so many species in several habitats
  • There are at the least 10 sorts of chasmosaurs, and the northern and southern species look totally different
  • The best way dinosaurs are distributed is totally different from how present mammals are distributed. Mammals are usually smaller however reside in massive ranges. Dinosaurs within the Cretaceous are usually bigger however dwelling in smaller areas
  • Longrich stated mammals could also be extra clever, “so they have an inclination to have extra versatile conduct, and adapt their conduct to their habitats.” “However, dinosaurs might have needed to adapt themselves bodily to outlive in a distinct habitat, and advanced new species. Maybe that’s the rationale why there are such a lot of species.”
  • Pentaceratops aquilonius is small (the scale of a buffalo), and a cousin of Triceratops
  • Scientists suppose Pentaceratops might have grown greater than the one discovered within the museum (which can have been a juvenile)
  • Pentaceratops has 5 horns on its face, in comparison with three horns on Triceratops
  • Pentaceratops additionally had a distinct formed frill and will have lived in Alberta
  • Pentaceratops aquilops is social gathering of the subfamily Chasmosaurinae (ceratopsians)
  • Chasmosaurs are identified for his or her massive forehead horns, and lengthy frills
  • Most lived in western Canada, western U.S., and northern Mexico
  • The primary Pentaceratops fossils had been present in 1921 (Pentaceratops sternbergii)
  • Pentaceratops lived 76-73 million years in the past, and most Pentaceratops have been discovered within the Kirtland Formation in New Mexico
  • Different dinosaurs present in that formation embrace Parasaurolophus cyrtocristatus, Sphaerotholus (pachycephalosaur), Nodocephalosaurus (armored dinosaur) and Bistahieversor (tyrannosaur). Additionally, Titanoceratops, which is nearer to Triceratops than Pentaceratops
  • Enjoyable reality: Dinosaurs lived on all of the seven continents, even Antarctica
