Came across this article, i hope who ever gets it allows scientists to study it. It raises an interesting question about nanotyranus being a subspecies and not a juvenile trex as is the current claim being made. Ill add the link where jack horner makes the claim where a lot of the dino species we know as seperate individuals are in fact juveniles due to bone density. Worth the watch on its own. Heres the main article: www.geologypage.com/2013/09/science-could-lose-duelling-dinos.html?m=0Heres horners video: Jack Horner: Shape-shifting dinosaurs:

No prob, i wish i could find more info regarding bone density, type of dinosaurs bone cell structure and maturity of dinos, kinda makes you look at gembone a little differently since you dont need any magnification to see cell structure

been watching these Jack Horner videos. Interesting how a lot of the Hell Creek dinosaurs, 13 known ones, are just juveniles and not a new species. The bone density topic is also interesting. I like how this Jack Horner talks about how museums and such don't cut their bones, but more is learned when cutting them.

oh.. also like J.HOrners topic about realistically making a dino from a chicken by adding characteristic traits like teeth, tail to end up with a dinosaur. J.Horner mentions extracting DNA from fossil is not possible and that making a dinosaur from a dinosaur is just not possible, but starting with a chicken is. Chickens are actually closer to dinosaurs than alligator and crocodiles.

Hey Santa, shove that under the tree for me this year.
Don't think my wife would approve of that for a center piece on the coffee table.

Haha, it'd have to replace the coffee table, and couch, and tv stand.
Jack horner actually advised Stephen Spielberg when filming jurrasic park. I saw a documentary a while ago (several years ) where they took chicken embryo and i want to say they mutated genes to get tails, teeth and scales. I think this was it, all 5 parts are on youtube Dinosaur to bird evolution 1of5:

Gotta watch the youtube 5-part vid (dinosaur/bird evolution) you posted a link to, transcendental, and thanks for posting it. Nosed around on the Bonhams' website and found the auction listing for the dueling dinos. www.bonhams.com/auctions/21076/lot/1032/Interesting that the juvenile t-rex had long arms, or do y'all believe the dinosaur was a sub-species(?) of t-rex, the Nanotyrannus? I guess if it were a juvenile t-rex, it "grew into" its arms?

The way i see it, the bones dont lie. The cell structure is a really convincing argument. However i think it will require cutting open a lot of individuals to get a large enough base for comparison. Great dane pups grow into their paws why not a trex? Then again im no expert so i look forward to further research on the subject... any subject related to dinos honestly lol guess im an amature earth science buff.... explains what im doing here

fossilman, I like him also. IMo, Montana seems like the place to be as far as finding the best preserved dino fossils. Not much as far as agatization, but that's a good thing when dealing with true fossils for study. He is active on his facebook page too. Pretty cool.
