Albertaceratops nesmoi MK II

Albertaceratops nesmoi MK II! It looks a lot better than my previous one, which is way too embarassing to link to now... You may have noticed but I am having fun with all these ceratopsians. It seems like I'm stuck in a ceratopsian phase right now...

I can't really comment much on Albertaceratops other than what's already been covered elsewhere. I don't think there's really anything done with this dinosaur other than the original description. But then again, what is there to do with a dinosaur known from a single skull and some fragments? Ah - someone should do functional morphology, like FEA - provided they have access to a huge scanner, that is... Not just in Albertaceratops but someone should look into stress distribution patterns in ceratopsian crania using FEA. Better yet, someone should look at pachycephalosaurs...

Anyway, I think it's the new paper but the pencil just came out too dark...and it started getting smudged so I couldn't really add any more to this. I am not liking this new paper at all...

Damn interweb won't let me read about Albertaceratops without plunking down like $25. If you have the paper, could you send it my way?

On the other hand, you're right, I've seen pictures of the skull, and it's pretty fragmentary. I'm actually MORE interested (as you've probably gathered) in Kirkland's "Octoceratops," which I'm beginning to think will never see the light of publication.

I'd like to see your take on Alaska's favorite centrosaurine, brother: Pachyrhinosaurus canadensis (Traumador would like it too, I think), perhaps?

Zach you're very right. I've always had a soft spot for Pachyrhinos.

Though this Albertaceratops drawing is awesome, and the want for a Pachyrhino is not a commetary on this drawing Manabu.

All me and Zach are of course getting at is the more the better ;p
Being inspired by the recent wave of ceratopsian stuff over here I took a look through my Tyrrell photos and came up with a couple shots of the Pipestone Creek Pachyrhinos.

I've put them up at my blog:

Sadly I only have one good shot with multiple specimens in it. The pachy age series was packed away and all over the place when I had a mere 30 minutes access to the Tyrrell's collection, and of course wanting pictures of a LOT of other things I only managed to track down the jaws (around minute 28/30 as I recall!).

Anyways loving the drawings their sweet!

I'm checking with Darren Tanke if he can get me anymore pics or info on the Pipestone Creek material.
Thanks guys:)

I will have to scrounge up some references for Pachyrhinosaurus, that should be my next ceratopsian!

Wow, I've been finding your blog through Traumador's and I have to say wow! Your dinosaur pencil drawings are very good and I look forward to seeing more!

R for beginners and intermediate users 3: plotting with colours

For my third post on my R tutorials for beginners and intermediate users, I shall finally touch on the subject matter that prompted me to start these tutorials - plotting with group structures in colour.

If you are familiar with R, then you may have noticed that assigning group structure is not all that straightforward. You can have a dataset that may have a column specifically for group structure such as this:

B0 B1 B2 Family
Acrocanthosaurus 0.308 -0.00329 3.28E-05 Allosauroidea
Allosaurus 0.302 -0.00285 2.04E-05 Allosauroidea
Archaeopteryx 0.142 -0.000871 2.98E-06 Aves
Bambiraptor 0.182 -0.00161 1.10E-05 Dromaeosauridae
Baryonychid 0.189 -0.00238 2.20E-05 Basal_Tetanurae
Carcharodontosaurus 0.369 -0.00502 5.82E-05 Allosauroidea
Carnotaurus 0.312 -0.00324 2.94E-05 Neoceratosauria
Ceratosaurus 0.377 -0.00522 6.07E-05 Neoceratosauria
Citipati 0.278 -0.00119 5.08E-06 Oviraptorosauria

The difference between Lion and Tiger skulls

A quick divergence from my usual dinosaurs, and I shall talk about big cats today. This is because to my greatest delight, I had discovered today a wonderful book. It is called The Felidæ of Rancho La Brea (Merriam and Stock 1932, Carnegie Institution of Washington publication, no. 422). As the title suggests it goes into details of felids from the Rancho La Brea, in particular Smilodon californicus (probably synonymous with S. fatalis), but also the American Cave Lion, Panthera atrox. The book is full of detailed descriptions, numerous measurements and beautiful figures. However, what really got me excited was, in their description and comparative anatomy of P. atrox, Merriam and Stock (1932) provide identification criteria for the Lion and Tiger, a translation of the one devised by the French palaeontologist Marcelin Boule in 1906. I have forever been looking for a set of rules for identifying lions and tigers and ultimately had to come up with a set of my own with a lot of help fro…

The fundamental problem with the Star Wars franchise

The sequel Star Wars Trilogy (so far Episodes VII and VIII) has been getting a lot of hate on the internet. While I think most of the hatred is just dreadful and ridiculous (like “Social Justice Warriors” taking over and making Star Wars too diverse and featuring too many strong female characters? Get out of here!), there are some legitimate criticisms, that I can relate to.

One such criticism is, that the new trilogy (especially The Last Jedi) effectively undoes the ending of The Return of the Jedi - in some ways rendering the struggles and sacrifices of the Rebel Alliance meaningless. As a viewer who watched the original trilogy conclude with the death of the Emperor, I presumed that the Empire came to an end, and with it the end of tyranny. I presumed that democracy would be reinstated in the form of a New Republic and the reconstruction of a New Jedi Order with Jedi Master Luke Skywalker at the helm. Peace is restored and all is good. I think that’s a nice ending.

But then the new S…
