Zegh's Dinosaur Thread

i was talking about this skin impression

. some thinks that the little " holes " are

anchor for quills

Ahhh, yes, I heard about that
It is entirely possible, and many "paleontographers" have gone that route, depicting their Ceratopsids with thick bristles, but personally I prefer caution untill more definite evidence (while I at the same time enjoy exploring speculation based on these kinds of compelling hints)
 
Zegh, do you like the Hollow Earth stuff? What is your opinion on such a thing (not actually existing but it's internal logic) and different eras of dinos living there?

Eh...

D:

No?

I've no clue man, I never explored the idea much, but if at gunpoint I guess I'd just be stammering something about it not making any more sense than dinosaurs in a submarine or dinosaurs on the moon (I saw that somewhere... )

By the way, I'm currently drawing dino-guide species #102 out of roughly 750 planned portraits. Just finished Alectrosaurus olseni (which, amongst many others, is the first time ever I draw it. With so many fucking species, this "complete list" is a first that I actually plan to actually finish)

I only draw species that are reasonably-ish complete, enough to warrant a portrait. All other species will still get a brief description in the book I plan to compile. How I then decide to go on about publishing will be a problem for the future, I just always wanted to do this.

As you may notice, I am also covering their teeth in a faggy, wussy, lefty, non-awesometacular manner. There is some back and forth regarding the visibility (and thus, awesomeness) of theropod teethage, but most level-headed consensus is that - regrettably - most animals (theropods included) would have their teeth covered by lips

As for the wings, an animal like Alectrosaurus would do absolutely nothing flight-related, whatsoever, and the wing-feathers are not intended for flying nor are they even related to any prospective future dream of flight (evolution is not goal-oriented), instead, they are developments meant to further communication or to display sexual maturity, or any such kind of thing, that - randomly - in smaller forms - become the road towards flight.
 
It's a great drawing but I feel like it could be someone's fursona

Don't :(
you trigger flashbacks of a dinosaur forum I used to frequent years ago, where this one belgian dude insisted we all had "inner animals", and then went on much much further than that, you can probably guess the general direction of it.

It took several belgians in the years to follow to repair my impression of belgians :(

TBH, you were on a forum for dinosaur weirdos, what did you expect?

To be fair, was back in the day when forums were fewer and attracted more serious people, and a few of those dino-nerds are actual paleontologists today, some have even described and named new taxa

Birds survived because they nested on the ground.

"Sixty-six million years ago, the world burned. An asteroid crashed to Earth with a force one million times larger than the largest atomic bomb, causing the extinction of the dinosaurs. But dinosaurs weren't the only ones that got hit hard -- in a new study, scientists learned that the planet's forests were decimated, leading to the extinction of tree-dwelling birds."

Might explain the survival of fully developed Charadriiforms and Procellariiforms (waders, gulls, petrels etc) that existed in the late cretaceous, since they all nest on rocky ledges.

The most common arboreal birds in the late mesozoic were the sparrow-like Enantiornithids, and they disappeared along with the dinosaurs.

A work-in-progress of an Oviraptorosaur found in Djadokhta, Mongolia, and specifically a member of the sub-family Oviraptorinae, dinosaurs with parrot-like beaks, and rounded heads with-or-without crests. The crests are difficult to predict, and in some species, what are almost certainly females, seem to sport crests. It could be that males did have more prominent ones (some crests are very tall), but there are also fully mature individuals of species that have no crest at all. Uncrested species are sometimes very closely related to crested forms - anyway

because of how peculiar and special these dinosaurs are, they are among the most eaglerly poached and smuggled species, mainly from Mongolia.
The one drawn above is unnamed, unstudied, illegally smuggled and offered at an auction at 65 000 USD. Since these specimens are unnamed and uncatalogued, they are nearly impossible to keep track of, because they have no identifying tags. I do suspect this specimen is among a dozen that were indeed repatriated back to Mongolia after the Dallas-based auction-house being taken to court.
This is nice to see, but it is because Mongolia specifically bans the private ownership of fossils. Some countries, such as the US, permit private fossil trade, resulting in some spectacular finds, such as an un-studied species of Allosaurus, being sold off to private collectors, this one in particular sold in some Paris auction. That's *an entire species* owned by some French motherfucker

Out of 19 Oviraptorines I deemed complete enough to warrant an illustration, a whole five were poached. Two out of these five were confiscated, turned over to science, and one has since recieved a proper analysis and a name. The second is being analyzed and will be named soon. The third is the one I drew above here, which - if I'm guessing correctly - is back in Mongolian gvt hands and will recieve study and analysis in due time

The final two are still in private collections, they seem - to my knowledge - untraceable. Someone's going through efforts to not be held accountable, but casts of the originals are popular in online fossil-shops.

A frustrating side effect is that there's a lot of bad science stemming from this as well. Provenance of the fossils is often ignored or surmised, with errors-of-margin of millions of years at the time, basically rendering such details pointless. Smaller exhibitions will often display chimerae of different casts based on undescribed, unstudied specimens, cutting-and-pasting together, creating "generic but awesome-looking" oviraptorids, often labelled "Oviraptor" for no apparent reason, other than the name "Oviraptor" having a nice ring to it. Oviraptor itself is an actual species, studied, catalogued and firmly estabished. A dinosaur can only be Oviraptor if it turns out to be Oviraptor, it's not a matter of opinion, but a matter of comparing every bone to the original Oviraptor, and seeing that they match. As I said, there's around 20 named dinos in the Oviraptorinae group, only one of them is Oviraptor, the other 19 are other closely related animals. But this is science, and science is boring and doesn't sell well in auctions or small, exciting exhibits

I know this is a very nerd-privilege-king of frustration, but as a dino-geek it really irks me. Despite the unethicalness of it all, these fossils represent actual living animals. I want to include them in my guide, nameless, analysisless, provenanceless, because they were actual living, breathing beings, before becoming smuggled pieces of contraband

The above specimen is, in my guide, labelled simply "Online, Djadokhta"

Urgh...

Are you getting paid for this exhaustive, highly specialized knowledge?

Nobody gives enough of a fuck to pay someone to know shit about dinosaurs :V

That said, I'm gonna see if I'll be able to make a krone or two by e-publishing this dino-compendium. It'd be neat!

In fact, just recently, one of the hardest working non-professional dinosaur experts, Mickey Mortimer, got a chunk of his fanatically detailed databased plagiarized. Nobody pays him for compiling one of the most impressive measurement and specimen databases in the world - and on top of that, paid people rip him off with impunity. Nobody cares. Well, except poor Mickey and those who care about him.

This T-Rex just got BUMPED.
 
Cool
I actually most like the coloration, how they're both in this blue-ish shadow, while the upper half of the canyon wall is bathed in sunlight :V
