My Eight Favorite Dinosaur 

Troodon is famous for being one of the smartest dinosaurs based on their cerebrum to brain volume ratio, and as such its brain was comparable in part to that of modern birds. It had bony tympanic membranes in its inner ear. It also lived pretty late in the Mesozoic, from 77.5 to 69 million years ago in the Campanian to the Maastrichtian age of the Late Cretaceous. It also possibly lived later, as shown in the documentary Dinosaur Revolution. I’m not crying over the poor Troodon in that documentary. I just have a twig in my eye, or a log. It had teeth with prominent, wounding serrations, which was unique at the time of its discovery and very similar to those of herbivores, suggesting that Troodon was at least partially omnivorous. It was fairly small, only 2.4 meters long, and about 2/3 the height of an average man. It had very thin legs, implying that it could run fairly fast, raising its retractable claws up off the ground when doing so. 



The animaly Stenonychosaurus is actually another species of Troodon, and trust me, if Troodon had been able to continue to evolve and evolved sentience, it would not have evolved to look anthropormophic (like a human) as Dale Russell said.I mean seriously can you imagine a more egotistical thing to think? That the way we look is obviously the only way a sentient being can look? Jesus Mary Joseph and all the freaking saints. Yes, I grew up Catholic. Yes, I still sometimes swear like a Catholic. Please move on. Troodon is one of the most derived members of its family and pretty much with 100% certainty had feathers, given its close relationship to birds and the general feathered state of clades much more basal than Troodontidae. It was found in many different places such as the Two Medicine Formation of Montana, the Dinosaur Park Formation and Horseshoe Canyon Formation of Alberta, the Prince Creek Formation of Alaska, the Hell Creek Formation, Lance Formation, and Scollard Formation. It probably favored cooler climates given its distribution and abundance in the north and even Arctic areas. It also has possibly found more further south in the Javelina Formation in Texas and the Kirtland Formation in New Mexico. 



It probably was a predator in some form given that it had a sickle claw on its foot and good binocular vision, however it was also probably an omnivore given its teeth and the shape of its jaw, which was similar to that of an iguana (and iguanas are herbivores.) The large serrations that indicated it could eat plants are called denticles, and its grasping hands and large brain are actually characteristics shared with herbivorous omnivorous mammals like primates and the raccoon. In northern sites Troodon actually has much larger teeth than ones in southern sites, indicating that it was larger in the north and able to hunt larger animals for prey given that there were fewer tyrannosaurids up there. Furthermore, the lack of wear in the north indicates mainly soft food - so it probably just ate meat in these climates and not tough plant matter. It reached adult size in 3-5 years. 



Troodon nests and eggs have been discovered. The nests were built from sediments and were disc shapes, and had between 16 and 24 eggs. The eggs were shaped like elongated teardrops, with the tapered ends pointed downward and imbedded in the sediment. The reproductive biology of Troodon is somewhere intermediate between crocodiles and birds- the eggs were grouped in pairs which would suggest that it had two oviducts like crocodiles, unlike birds which have one; Troodon also laid eggs of medium size and medium number, unlike crocodiles who lay many small eggs, and birds who lay few large eggs. It also potentially laid eggs iteratively, laying a pair of eggs every one or two days, and delaying brooding until all eggs were laid to ensure that all of them hatched at once. The embryos had advanced skeletal development, implying that they were precocial (or, relatively mature and mobile young), and probably didn’t remain in the nest after hatching. Given the body ratio to egg volume, it actually was very likely that the males in a pair brood the eggs and the females did not, a characteristic that maniraptoran dinosaurs and basal birds probably shared. 



Again, I refuse to talk about “the dinosauroid” more than it’s a dumb, dumb concept. 


Shout out goes to free-my-wonderland!

A lot of people have designed hypothetical intelligent dinosaurs before, but the Brontosapiens is unique in descending from the gigantic, ponderous sauropod lineage. Behold the race of armoured, intelligent plant eaters with sound-amplifying air sacs and a penchant for smoking pipes.


Battle of the Titans - Troodon life-size replica

From October till the end of January I was working at Hall Train Studios for Seonna Taisteal Travelling Exhibit inc.’s “Battle of the Titans.” The show opened on January 26th 2013 at the Royal Botanical Gardens and will run there until April 7th 2013.  This is a another part of the exhibit (click here to see life size T-Rex and Triceratops) life-size replica of a troodon.

Unbelievable Dinos:  Anchiornis

Some dinosaurs had russet-colored feathers, scientists say, and this jazzy specimen had a Mohawk crest and stripes. The Anchiornis huxleyi was a small, feathered, two-legged dinosaur that lived roughly 150 million years ago. The animal weighed just about four ounces (110 grams) and appears to have had a dark gray or black body and wings with white feathers that gave it a stripe pattern. It also had a reddish-brown crest and speckles on the face.

An experimental, cave-art-like rendition of dinosaurs. The mid-size tyrannosaur, Gorgosaurus, has just killed an Edmontosaurus-like herbivore, two bird-like Troodonts are closing in to share the kill. There is more than enough to go around for everyone.

As time has gone on, I’ve really warmed up to the new WWD movie, I’ve gotten over it’s not going to be like the original series as we hoped and judging it by what it is.

And I think it has some of the best dinosaurs in movie history ever. Just look at that Troodon, it’s body feathers are pennaceous, but less complex, like those of an emu (as you would expect in an animal that has long since lost the ability to fly). It’s got primaries coming off of the second finger, and I swear those like the remnants of leg wings on its leg. Sure it’s got a few things iffy about it, the scaly face and fingers come to mind, but everything else is great. 

Even if the film itself turns out to be not that great, we still get to see this bugger running around.

Umh, I’m not sure that star is going to stay there, you might want to reconsider where you put it, buddy.

Decorating conifer trees for christmas is sooooo Carboniferous, every dinosaur knows that decorating your herd’s matriarch is the way to go in the Campanian times.

Happy holidays! ;)
