Zegh's Dinosaur Thread

Blue eggs? That's a funny thought.
Always assumed they be white...ish. Or some camo color depending on surroundings. Blue is weird tho. Kinda rocky?

That's the fun part, any kind of dino-related color and its significance has been sort of overlooked till now. These particular eggs were blue right there on the surface

the same way that some eqxuisitely preserved dinos have their coloring/patterning visible with the naked eye (the "lemur stripy" tail of Sinosauropteryx as well as the densely striped tail feathers of Caudipteryx) - but spotting this leads the way to looking for it, so lately researchers are checking a lot of long known fossils for traces of pigmentation. Confuciusornis has been tested, and was probably starkly black and white, Archaeopteryx has been tested, and has likely black feathers at least some parts of the body, Sinornithosaurus turns out to have been reddish orange speckled and so on.
A similar approach to allready known eggs could possibly reveal more colorations or hints of it

Dinosaurs laid eggs of widely differing shapes, these famous ones are elongated, but even related dinosaurs laid very different eggs, such as completely spherical. The laying of eggs varied too, in what pattern their laid, what type of nest etc. Some would probably be communally cared for, others might have been abandoned, like crocodiles. So, like all this variation, color would play a role too

Oh cool!
By the way, "sort of dino-related", I know a couple of paleontologists who would not hesitate for a moment, to categorize news like that as "dinosaur news", to the point where they'll refer to Triceratops, Velociraptor, Diplodocus et al., as "non-avian dinosaurs" :D

But yeah, cool stuff, I always wanted to hear about actually documented cassowary attacks/kills

Cool
Todays crocodiles are kind of one aspect only, of a larger, much more diverse group - it's kind of like imagining seals being the only remnants left of all the mammal carnivores, in such a way that "mammal carnivore" is automatically assumed to be fat and aquatic. In the mesozoic, many crocodile species were shaped like - and took the biological niches of - small jackals, for example, fox-like animals, long slender legs, agile bodies, active lifestyle
 
I've always imagined Tyrannosaurus kinda like how elephants or lions carry fur. Neither two are poofy "like a chicken", both appear naked from a distance, except one has sparse, long, thin hairs - which would certainly fit Tyrannosaurus, other is a very fine hair, with big separate lumps (like chickens have poofy bodies, but totally naked feet, for example)

Either way, there's no new consensus here, other than apparently an update to the dino-design in Saurian
 
Indeed, nearly all Griman Creek formation dinosaurs are opalized - it simply was the mineral present there to replace the vacancy left by the decomposition of the organic matter

(also, the last two links there are the only links worth a damn ;D Straight to the primary source!)
 
Indeed, a new Spinosaurus was described only recently (which also showed us that Spinosaurus had freakish short legs), by Ibrahim et al.

untill then, though, the only certain Spinosaurus postcranial remains (although it was far from complete, consisting of the famous sail, and some other bones. But, by most standards, this is often considered complete enough), as well as being the holotype, was bombed to pieces during WW2. Along went also the Carcharodontosaurus holotype, as well as Aegyptosaurus.

Carcharodontosaurus and Spinosaurus have recieved neotypes since, but Aegyptosaurus is considered a "nomen dubium", which means no dinosaur remains will ever be compared to whatever descriptions remain, and as such, the name is practically abandoned.
