Show us your duck-billed dinosaurs material.

[Bobby Rico]

Hi all

I really think the Hadrosaurs were very cool dinosaurs and not just as a food source for the T.rex.  So in celebration of the great beasts please show us your Hadrosaurs material . Hadrosaurs are dinosaurs that are members of the family Hadrosauridae, and include ornithopods such as Edmontosaurus and Parasaurolophus. They were common herbivores in the Upper Cretaceous Period of what are now Asia, Europe and North America. 

 

Edmontosaurus annectens  Metacarpal V found at the famous Hell Creek Formation... 

Late Cretaceous Period  Montana. The missing one in photo that Frank @Troodon sent me when he kindly identified it for me before I purchased for a real steal.
As our village has started to put up their Christmas decorations early to offer some much needed joy , so I made a Santa to Edmontosaurus scale drawing I think it will make a great greetings card and adds a little whimsy.

 

Stay safe and sound Bobby

Fun fact Benjamin Waterhouse Hawkins mounted Hadrosaurus , the first mounted dinosaur skeleton in the world in Philadelphia in 1868. 

[LordTrilobite]

Yes, I have a few hadrosaur fossils... 

 

Here are some of my best ones. Don't forget to press full screen on the bottom right for the 3d models!

Edmontosaurus annectens fossils from the Hell Creek formation.

And then there's this beauty from the Lance formation. A mostly complete braincase of an Edmontosaurus annectens. It also has a very large hole in the top. Bite mark perhaps?
I still need to make some better photos.

 

Saurolophine hadrosaur humerus. Probably Brachylophosaurini. From the Judith River formation, Montana.

 

Juvenile hadrosaur humerus. I'm thinking probably Hypacrosaurus due to the deltopectoral cresting being fairly substantial for such a small individual. Probably from Two Medicine formation.

Well, @LordTrilobite is a tough act to follow. Here are my meager hadrosaur fossils. 

An Edmontosaurus annectens tooth in matrix from the Hell Creek Formation.

 

And a hadrosaur rib bone fragment from the Two Medicine Formation in Montana that was part of my secret Santa last year. 

 

[Flx]

Edmontosaurus Scapula from Hell Creek Fm. It is about 1m long. 

I bought this fossil in a plaster jacket and prepped it last year.

 

(Ignore the other fossils in the picture. Those are not duck billed dino.

I hope to post some this evening after work, and hope to get them on here before troodon gets his amazing collection up.  : )

 

 

[Troodon]

Ha ha too late. @jpc

 

Edmontosaur's could exceed size of a T rex.  Here is a femur that is about the same size as the Trex known as  Sue.

Still in jacket 50 " (127 cm) long 

 

Collecting at an Edmontosaurus bonebed provides the opportunity to see the growth series in the bones 

Here are several Humeri ranging from 3" to 22" (7.6 to 59 cm)

 

 

[Flx]

@Troodon Dou you know if your humeri were embedded simultanously (eg same flooding event)?

[Troodon]

A sedimentologist from the Field  Museum came out one year to look at our deposit.   He felt there were multiple events at this bonebed.  So I cannot say for sure if these were from one or more.

I won an alleged hadrosaur possible pubis from the Two Medicine Formation, Montana in as a bonus item in an auction here two or three years back. 

Here as advertised :

But unfortunately it arrived like this  :

 

[Ruger9a]

Ouch, that had to hurt!

Yeah.

But at least it wasn't a brachiopod.

[Ruger9a]

haha...  Yes, at least it wasn't a brachiopod!!!!

[Bobby Rico]

Wow thank you all much appreciated @LordTrilobite beautiful specimens love the skin impressions. 
@thelivingdead531 Nice Secret Santa gift .

@Flx very impressive and looks nicely prepared.

That is one big creature and love the size comparison Humeri.

 

@Tidgy's Dad it is so sad when fossil get damaged it transit . I had a few disasters myself.  
 

thanks all

Here are a few from my collection.  All self-collected (and prepped) from the Lance Fm here in eastern Wyoming.  The scale bar is in cm and mm.  

This first one is a piece of ossified tendon.  The tendons turn to bone during the animal's life.  Similar things happen in many kinds of birds.  Hadrosaurs had a whole network of them running along the neural spine. Little pieces are pretty common in Lance Fm bone beds, but this one is pretty long, and shows the bifurcated end.  Ceratopsians also had these, but I found this one with some other hadrosaur bones.  (From what  have seen, they tend to be bigger in ceratopsians).  

 

This next one is a complete caudal vert.  This one is from a mutli-species bone bed where almost all the other finds were considerably smaller.  (There is an anthill next to this bone bed that is my richest Cretaceous mammal site).  I no longer go to this ranch because they want more money than I can afford to collect.  Only the tip of the neural spine was sticking out of the sandstone.

 

This next one is one of my coolest fossils.  This is a maxilla of a young hadrosaur found at a site I call Short-eared Owl Blowout.  When I found this site, I heard a dog barking form up in the sky.  Turns out it was a short-eared owl.  I imagine he/she was defending its territory, so I left and came back another day.  And found this guy.   Only a wee bit was exposed when I found it.  There is about 30 hrs of prep on this one.

 

. 

 

And last but not least, many years ago,  one of my rancher friends called me up and said that he had found a dinosaur while bulldozing to repair his fence line.  Come on out, he said.  He had bulldozed through what might have been a pretty good specimen, but a lot of it was trashed.  I was tickled pink to find this chunk.  That is the impression of a bulldozed femur, and a ton of skin impression on the rest of the  rock.  

 

I have a pile of teeth, too... somewhere.  Including some very small baby teeth.

Great stuff!

Would be interesting to see the finds

A small Hadrosaur from southwest France

Canardia garonnensis. A maxylary and a quadrate

Wow

 

Dont see many from France.  Great fossil

[caterpillar]

Indeed, very rare. It's one of the latest species of Hadrosaur. I've found it 1m under the K/T boundary

[jpc]

Very nice, caterplillar.  I have never heard of this species... Canardia... great name.  (For those who missed it, 'canard' is French for duck).

I would have to try to find them...  : )

thank you so much very stunning specimens. Really  love maxilla of a young hadrosaur and a owl story too. Cheers Bobby

Wow incredible thank you so much for adding to my thread. 

[Bobby Rico]

I started this thread with a little offering of a Metacarpal and then the forum added  all the real beautiful specimens thank you.

 

I don’t really have much Dinosaur material and I do treasure all I have so here’s my Edmontosaurus toe bones, South Dakota, Hell Creek Fm. 

I believe the first fossils named Edmontosaurus were discovered in southern Alberta  and it was named after Edmonton, the capital city, in the Horseshoe Canyon Formation. 

 

[jpc]

Ooohhh. and I see some teeth on the side.
