The next question from that anonymous person:

“What is your opinion on Barney, what shoddy craftsmenship, right? Right down to those GARRISH toes.” - Anonymous

I completely agree, Anonymous. Also, for this post, I have redrawn Barney and his friends as accurate and contemporaneous dinosaurs: a subadult Daspletosaurus, a young Arrhinoceratops, a subadult Montanoceratops, and a young Saurolophus. This would obviously make for a much better children’s show.


Happy 2015- Here’s A Dinosaur!

Continuing the tradition of posting a dinosaur photo to enter the new year, here’s the 70 million year old skull of the “no nose-horn face” Arrhinoceratops. This stellar specimen was collected in 1923 near Drumheller, Alberta, and was named by legendary ROM Palaeontologist William Parks. William Parks had previously named the famous hadrosaurs Parasaurolophus and the Reddit famous Lambeosaurus.

Looking Forward To A Dinoriffic 2015
This year we’ll all learn lots more about horned dinosaurs- on January 24/25 we’ll be unveiling a brand new species of ceratopsian! The palaeo department will be out in force talking about their work and their latest discoveries. We’ll also have a few other world renowned palaeontologists from other AWESOME institutions, plus the AMAZING, if not the BEST, palaeo communicator the internet/globe has ever seen. More to come!

More information!

The no-nose horned face, Arrhinoceratops (1925)

Phylum : Chordata
Class : Reptilia
Order : Ornithischia
Family : Ceratopsidae
Subfamily : Chasmosaurinae
Genus : Arrhinoceratops
Species : A. brachyops

  • Late Cretaceous (70,6 - 70 Ma)
  • 4,5 m long and 1 300 kg (size)
  • Horseshoe caynon formation, Canada (map)

When its type fossil was first discovered, in Utah in 1923, Arrhinoceratops seemed to be missing the small nose horn possessed by most ceratopsians–hence its name, Greek for “no-nose horned face.” Wouldn’t you know it, Arrhinoceratops had a horn after all, making it a very close cousin of Triceratops and Torosaurus (which may have been the same dinosaur). This small mixup aside, Arrhinoceratops was very much like other ceratopsians of the late Cretaceous period, a four-footed, elephant-sized herbivore that likely used its long horns to battle other males for the right to mate.

Arrhinoceratops had a short, deep, wide face with large nostrils. Its two brow horns were moderately long, very pointed, and curved forward. The neck frill was broad with small, oval fenestrae (openings), and was rounded. The only skull of Arrhinoceratops to be found was slightly crushed and distorted, making it difficult to understand the pattern of the skull bones. Paleontologists don’t know what the rest of its body looked like.

Arrhinoceratops lived during the late Cretaceous (70-65 million years ago). It was also closely related to Torosaurus, Chasmosaurus, Pentaceratops, and Triceratops.

Dinosaur bone bed a real gold mine

On the rocky slopes of Alberta’s badlands, tucked away beneath a pre-historic riverbed, scientists unearthed a trove of fossils from one of the rarest horned dinosaurs in North America.

The discovery on what is now the banks of Red Deer River north of Drumheller marked the first time in more than half a century that paleontologists had found remains of arrhinoceratops.  Read more…
