Replica of Stan the T-rex Going to Japan

[Troodon]

Interested in seeing what it takes to put a replica T-rex of Stan together for a museum in Japan.  Pete Larsen president of the Black Hills Institute walks us through a build through his Twitter feed.

 

The mount starts in the hips, ilium and sacrum

 

To mount the legs and pelvis (one operation) it takes 4 holders for the legs, 2 holders for the body and tail pipes, 1 welder and a spotter to see that it is anatomically sound

 

Vertebrae added to the tail and getting longer.

 

And longer...

 

And longer

 

Pubes, ischia and fibulae to the mount

 

Gastralia are ready to mount on the skeleton

 

 

Mounting the dorsal and cervical vertebrae, creating a fitting between cervical 9 and 10, so that the neck is a separate section.

 

Ribs mounted

 

Dorsal ribs 1 and 4 need steel inorder to support the pectoral girdle.

 

Scapula-coracoids also need steel to connect to the ribs and support the arms.

 

Finished mounting the chevrons 

 

Scapula-coracoids and the four supporting ribs mounted

 

Those four ribs and the scalp-coracoids need implanted steel and fittings to support themselves and the arms, while still being removable for their shipment

 

Arms added,  installed the furcula

 

Adjusted the Ribs

 

Mounted the Crevical ribs

 

Left Foot

Foot and base ready for paint

What!  When were you there?  We were there two days ago and it looked exactly like this.  Did I miss you by minutes?  We had dinner at the German place next door.  Were you there as well?   

 

Or did I take these photos and send them to you in my sleep? 

 

Pete told us that the lower jaw on this one is going to be movable (up and down).

Ha ha, Good food at that german resturant.  No heading there in a few weeks this is from Pete twitter feed.  What brought you to the BHI?

How big was the box for this thing?  

[Jaimin013]

This is really impressive work and it's really intriguing how they put it all together!

We did a Tate Museum members only outing to the Black Hills... Hot Springs mammoth Site, SD School of Mines Geology Museum, BHIGR and an ammonite hunt.  A good time was had by all.

Wow thats a cool time, I'm sure everyone enjoyed it.  My places to visit on rainy collecting days.

Finished the feet and gastralia basket

I had the chance to enjoy it when I went to the Royal Science Museum in Bruxelles.

Nice beast. It is unfortunate that it is not coming to Mifune dinosaur Museum.

 

Where does it go?

I know there is already one cast at the National museum of science in Tokyo. Maybe Fukui?

No mention of a specific locality,  just Japan

Getting the skull ready for mounting with a movable jaw.

 

[Troodon]

All finished ready for it's new home

[Miocene_Mason]

What a beautiful beast! Very cool process, thanks for sharing!

The word is hugely overused, but that really is awesome!

Pete Larsen explains his jaw movement feature:

With our latest Stan mount, we’ve engineered a new feature - opening and closing the jaws. In order to make sure this innovation will not break down over time, we added extra steel, connected to the internal frame.

 

The jaws rotate about an axis inside the quadrate. Here you can see the bolt that acts as the center of rotation.

 

An eyebolt is threaded into the steel within the articular of the lower jaw. The bolt in the quadrate is threaded through the eyebolt. Together they act as the hinge allowing the jaws to open and close.

 

Once the jaws are in position on the upside down skull, we need a way to arrest the motion of the jaws in different positions.

 

This is accomplished with a slotted bar attached to the ectopterygoids and the surangulars.

 

Once the skull is mounted, we can display it completely closed.

 

Or completely open.

Huh, I've never seen a trex skull with its mouth closed. Interesting!
