Congrats to our European members!  They get their first REAL Tyrannosaurus on display!   And Tristan is a nice specimen too!

First since the British Museum took down the Dynamosaurus holotype!

Although I visited the naturkunde museum Berlin about three weeks ago, I'm gonna see this T-rex hopefully by next year. Think it will be a unforgettable experience.


In two years the first permanent T-rex will be exposed in Naturalis, The Netherlands. And about a year later their adding five!!!! Triceratops fossils along with it. Looking forward to that too.

Wow! Tristan is a real beauty! Congrats.
How big is Tristan compared to the other well known specimens?

Maybe a very dum question
But why is there a piece of bone partialy covering its eye socket?
Just look at the skull image and you can see the part on the right side of the picture
What is that?

Which bone do you mean? The bone coming in from behind the eye socket, with a foreward-pointing flange? I believe that's the postorbital. The one in front of the eye socket is the lacrimal, if I'm not mistaken. Tyrannosaurus had forward-facing eyes, so a bone that "covers" it from the side doesn't interfere with anything. If you feel the right side of your own eye socket, there's a strut of bone, called the postorbital bar, that does pretty much the same thing, but lots of mammals don't have it (opossums, mice, bats, rhinos).

This is the one i was refering to

Yep, that's the postorbital, which in animals with binocular version, partially occludes the orbit in lateral view. I don't know what kinds of muscles it anchors; possibly extrinsic oculars and things like that. Probably provides some structural support too.

Ok
Thank you very much for clearing this up for me

Tyrannosaurs is known to have that "keyhole" shaped eye socket while other Tyrannosauroids like say Gorgosaurus had a more circular shape and Daspletosaurus had an oval shaped one.

Interesting, didn't know that!
