We will start off this week with what every dinosaur collector would love to have in their collection an Opalized theropod dinosaur tooth from Lightning Ridge, Australia

I will leave you this week with a T.rex specimen that most folks are unaware of.  Its Paul Sereno’s, University of Chicago, subadult arm.

This is a published specimen: UCRC-PV1.  This is the ONLY known complete arm of a T rex.   And no they are not longer in a subadult as some who claim longer arms and claws in Nanotyrannus magically become smaller in an adult T-rex

Yes fossil Friday  :) Thanks Frank 

 

If you don’t mind I would like to run with the T.Rex theme . I really enjoy looking at old black and white photos. Here is a couple of Barnum Brown . First is him with his T.tex the bones are misguided and mounted more like a Kangaroo but still a great photo . The second one is for Adam and Tidgy a bit of eye candy.

legendary man , shown here at work on a land tortoise fossil, Hall of Vertebrate Origins, 1930.

It is also the only one with a furcula.  Sereno's rex came from the same ranch my wife and I got married on (but we got married on a ceratopsian, not a rex).  

 

As a lesson to folks who do not live out here, Sereno is no longer welcome in the whole county where this came from because the section of BLM (Federal gov't) land that this specimen was on was surrounded by private land and Paul did not even consider talking to the rancher who owned the land.  He was busted trespassing and burnt his bridge not only with the rancher, but all of his neighbors.  

 

Get permission to access private property, my friends.  Especially in the American west.

With all this love for Tyrannosaurids, I think it's time to highlight another hadrosaur, and give it some love as well.

 

Magnapaulia. One of the biggest hadrosaurs known, and the largest Lambeosaurine. It's quite big at some 12 meters or more.

The beak and lower jaw.

Yeah Parasaurolophus is great, such a cool animal.

 

Concerning that crest neck attachment, so far as I know the consensus is that that vertebra is pathologic and that there was no connection as there are no muscle attachments visible on the crest itself.

Though I have heard some recent rumours of a new specimen that has soft tissues preserved on the sides of the crest in the longitudinal furrows. But we'll have to wait for a publication for more info on this.
