Teaching kids to question things

Not palaeo or art I'm afraid, but kind of along the lines of critical thinking. When I was a kid, I lived in the United States. I also went to elementary (primary) school there. I forgot which grade it was or what class it was in, but one day, my teacher showed a video about the possibility that the Earth could be flat and how we can perceive it to be round; i.e. explanations on why the Earth looks round from outer space when it is really flat (something to do with light bending due to gravity). I was shocked, but apparently, our teacher's aim was to try and engage the kids to question established ideas, which in and of itself is fine. However, to this day, I fail to understand how she thought it would be appropriate to teach kids to question something that is observational, and present an alternative idea that has repeatedly been falsified. Fortunately (and perhaps surprisingly), our class was smart enough, and the video was met with the appropriate scepticism. However, I now wonder how many of my classmates were affected by this video...

Understandably, my father was enraged when I told him that evening during dinner.

I think what the teacher did was ok, but could have clarified at some point, the actual fact of the earth's spherical nature. I have discovered that a major theory concerning the occurrence of preserved soft-tissue is bogus. They're still teaching the wrong thing about it in university. Every 3-d formed rock and stone is petrified tissue from dinosaur feeding activity.Goggle THE SECRET LIFE of ROCKS, then my name.

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…

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…
