Episode 219 is all about Nedoceratops, the lesser identified ceratopsian within the Triceratops vs Torosaurus debate.
We additionally interview Denver Fowler & Liz Freedman Fowler, paleontologists who work on the Badlands Dinosaur Museum. Denver is the curator. Liz is an Affiliate Professor of Biology at Dickinson State College. They’ve labored on a nodosaur, tyrannosaur, ceratopsians, hadrosaurs, and different dinosaurs everywhere in the world. Observe Denver on twitter and take a look at their upcoming convention.

On this episode, we focus on:
Information:
- A brand new sauropod from Tanzania, Wamweracaudia, emerges from an evaluation of 100+ sauropods supply
- Dave Hone has a survey as much as get suggestions on his analysis impression supply
- Lauritzen Gardens in Omaha Nebraska has a brand new indoor exhibit known as Dinosaur UpRoar supply
- There’s a brand new T. rex Science Heart within the works in Charleston, West Virginia supply
- Polish graphic designer Jans Bajtlik made a tie that includes a map of Warsaw and dinosaurs supply
- Lifeless Sound launched a brief animated dinosaur story known as Sharp Enamel supply
The dinosaur of the day: Nedoceratops
- Ceratopsid that lived within the Late Cretaceous in what’s now Wyoming, North America (Lance Formation)
- A part of the Triceratops / Torosaurus debate (mentioned in episode Ultrasaurus – Episode 21)
- Controversial genus, some assume it’s a legitimate genus and others assume it’s a part of the Triceratops progress collection
- Identified from one cranium
- Cranium was 2.6 ft (1.8 m) lengthy
- Cranium was present in 1891 close to Lightning Creek
- Cranium has a rounded stump as a substitute of a nasal horn and the forehead horns are nearly vertical. In any other case, it’s much like a Triceratops cranium, however bigger, and with a brief face. Additionally, has massive holes within the frill (completely different sizes), not like Triceratops (may very well be a pathology or genetic)
- Lull thought the holes within the frill have been from “unintended gorings” from one other dinosaur, however it’s not clear if that’s true
- Sort species is Nedoceratops hatcheri
- Title means “inadequate horned face” (for lack of a nasal horn)
- Nedoceratops has a pair different names: Diceratops and Diceratus
- Marsh began describing Nedoceratops within the 1800s, as a part of his Ceratopsidae monograph. Nevertheless, he died of pneumonia in 1899 earlier than ending, and John Bell Hatcher completed the Triceratops part (however he died in 1904 of typhoid fever earlier than ending), so Richard Swann Lull completed the monograph in 1905, and revealed Hatcher’s description of the cranium individually and named it Diceratops hatcheri (means “two horned face”
- Lull didn’t really consider it was a separate genus (thought it was a pathology), and in 1933 renamed it as Triceratops hatcheri
- In 2007, Andrey Sergeevich Ukrainsky renamed Diceratops / Triceratops as Nedoceratops (the title Diceratops was used for an insect)
- Nevertheless, Octávio Mateus didn’t notice Ukrainsky had renamed the dinosaur, and renamed it Diceratus in 2008. Diceratus is now thought of to be a junior synonym (because the title Nedoceratops got here first)
- Debate about it being a part of the Triceratops progress collection (in between Triceratops and Torosaurus), and Scannella and Horner proposed Nedoceratops misplaced its nasal horn whereas alive or throughout fossilization. Nevertheless, Farke mentioned the form of the horns and the feel of the bone counsel Nedoceratops was an “previous grownup” In 2013 Leonardo Maiorino and others discovered Triceratops and Torosaurus to be distinct genera
- Farke prompt the holes within the frill weren’t from gorings however from “the results of bone resorption in an space of the frill that was already skinny to start with.”
- Maiorino discovered that Nedoceratops “has a variable place relative to Triceratops and Torosaurus,” relying on what you’re , and that the scale of the cranium might assist the speculation of it being an intermediate between the 2, however the form of the cranium could be very completely different
- Some scientists assume Nedoceratops may very well be a direct ancestor to Triceratops, or its nearest relative
- Want extra fossils to know for certain about Nedoceratops, and to look at the bone microstructure
Enjoyable Reality:
Dinosaurs dominated the land on Earth for longer than every other group of animals.
