Allosaurus fragilis

Okee dokey - continuing on with the theme, I've started tracing out this hand-drawn Allosaurus. The original was drawn ages ago - I can't really remember when. But it's up on my website (http://www.geocities.jp/raptors_nest_theropoda/).

Anyway, since I already have a digital version, all I need to do now is to import it into Illustrator and trace it out.

The next step is to use the Pen Tool and just manually trace out the outline of the drawing. This is actually quite time consuming and it's taking as long or longer than it'd take me to draw a dinosaur from scratch...

Now this is what it looks like with the tracing and the coloured-in eyeball superimposed (right).

And without the original (left). Unfortunately, this is as far as I got today, and my neck and back is starting to hurt since I've been crouching in front of my laptop for over 2 hours now....I'll resume some time later and start on colouring - I am not looking forward to that process. Actually, the teeth are already coloured in, though you can't really see it.

Wow...I'm glad you posted this. I've always wondered how people do digital paleoart. The jet has amazing colors...you did that in photoshop? I took a class in Photoshop and I don't think I came away with anything useful. We worked in small groups and all the people who had experience took over and did everything.

I'm really impressed with the jet...can't wait to see Allosaurus!

I basically just played around with Photoshop until I found some effects I liked so I'm completely self taught - I don't know if I actually represent the mainstream digital artists techniques...

I really need to take a Photoshop class (note to self: buy Photoshop). Manabu, have you ever penciled a picture, then inked it, erased the pencil lines and thought, "Damn, I liked the pencils more." That happens to me all the freaking time.

Yeah, that's why I rarely go beyond pencil sketches...

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

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…

Top 10 scientifically important theropod dinosaurs of all time (off the top of my head)

I thought I'd do a fun post for once. And since list based articles are the norm for fun on the internet, I thought I'd do one on dinosaurs, but given that I know most about theropods, I've decided to restrict my list to theropods (...maybe in a future post, I'll do other clades).

My ranking is based mostly on scientific importance so it may not reflect awesomeness, and it is obviously subjective as to how I rank importance to science. For instance, interesting discoveries or unique palaeobiology are ranked relatively low compared to wealth of information and data or completely revolutionising our understanding of the evolution of theropods.

So here are my top 10 scientifically important theropod dinosaurs of all time (off the top of my head)

10. Megalosaurus

Being the first dinosaur to be named, Megalosaurus automatically deserves a spot on this list, but given the fragmentary nature of known fossil specimens, and being mostly useless as a meaningful source for biologi…
