Is Daspletosaurus wilsoni valid?

- Daspletosaurus wilsoni was described last year, and since then some researchers have wondered if it is its own species, or just an odd specimen of an already named species, and if anagenesis in tyrannosaurs is the pattern we see in the fossil record.

Tyrannosaur evolution is so fascinating, and the mystery adds to that.
I have such a soft spot for Dasplet honestly, he has become my favourite big theropod in recent years. It’s still wild that we can’t quite nail down his evolution through the timeline
what are you gonna do with the billion years you saved by dropping the -osaurus bit?
Is pretty cool, it's like the less popular but still super cool little brother to Tyrannosaurus
Despositosaurus seems chill af
I would bet it wasn't lol
OK. So basically, the theory I was told a while back isn't so robust after all and we're back to "don't know."
Thanks for updating us on this.
2:17 this is such a great graph, looks like a shitpost but is actually informative, wonderful!
Need me that crystal habits t shirt. Great anagenisis diagram too
Always great to see the rigors of scientific debate in action!
1:15 that’s my advisor ❤
The recently discovered Tyrannosaurus mcraensis adds support for Tyrannosaurus evolving in southwestern North America. The phylogenetic analysis in the paper also found that the tyrannosaurids assigned to Teratophoneini in the paper you covered here were actually closer to Tyrannosaurus than Daspletosaurus. Between this and the uncertain placement of Alioramini, it looks like it may be awhile before tyrannosaurid interrelationships are stable.
I fully agree. I think there's going to be a lot though, because from what I saw at SVP there are very opinionated ideas about tyrannosaur evolution.
I noticed that you both combed your hair and shaved before recording the last segment at 4:40. I'd have just left it until the next video. 😉😂 Interesting report about an interesting dinosaur!
It was specifically about the if you know you know bit. There were some heated discussions at the conference
Far out. Intriguing stuff. I love palaeontology. It’s like trying to put together lots of different puzzles, when you no-one knows how many puzzles there are, where the piece are and there is no box art😹
there mustve been some kind of war going on between the tyrannosaurini and the daspletosaurini to separate them like that
cool
The high heeled woman for comparison bugs me. What would Elsa say?
We did not create the graphic, and it is presenting an average woman, extended to a height of 2 m to act as a consistent measure. Men in these sorts of graphs are often assumed to be two meters, and while there are critiques to make this is one way to make it more clear. Personally I would say that the idea of comparison to a person needs to change from 2m, to something more representative of the mean, between 5.25 ft (1.6m), and 6 foot even (1.8m) as most of the human population falls within that bell curve. Unfortunately that isn't where the field, scientifically or within general paleoart is right now
