Nice specimen above.  I love seeing one in this state as they are being prepped and revealing what is hidden in the matrix.

I love Fridays.

Ok seeing as it is friday for me over in the good old uk, thought I would start off with this i found of the quetzalcoatlus holotype

Secondly Dimorphodon holotype found by Mary Anning 

And skull

[Troodon]

Its Friday and that means its Dino Fossil Friday

A new troodontid dinosaur, Almas ukhaa, from the Late Cretaceous deposits of the Djadokhta Formation at Ukhaa Tolgod, Mongolia

 

Rarely seen original of the complete Scelidosaurus (Armored Dino) holotype courtesy of NHM of London from the Lias of Charmouth on the Jurassic coast. Skeleton is shown prior to preparation. One of the best dino skeletons from the UK

 

Here's is the skull of Scelidosaurus harrisonii courtsey NHM London

 

 

The holotype skull of Nanotyrannus, once called Gorgosaurus, courtsey of the CMNH

 

Amazing eggs containing tiny dinosaur embryos from the Early Jurassic of South Africa. Embryos show eggs are from the sauropodomorph Massospondylus.        @HamptonsDoc @-Andy-  Something to strive to add to your collections since both of you are Eggers 

 

The first (and only named) dinosaur ever found in North Carolina: Hypsibema crassicauda, described by E.D. Cope in 1869 from this hadrosaur tail vertebra.

 

Less well known is that Cope described a second supposed North Carolina dinosaur at the same time: Hadrosaurus tripos. Unfortunately, it turned out to be a Pliocene baleen whale vertebra!  Oops see even famous paleontologists make mistakes.  So its okay to screw up an ID. 

 

The skull of this mosasaur specimen is slightly less than a meter long. The mosasaur tooth embedded under one eye is the first evidence for a nonlethal mosasaur attack on one of its own kind

 

A hand claw from the holotype of Anzu wyliei courtsey of the Carnegie MNH, Hell Creek Formation, South Dakota.  One mean dude and you were worried about Mr. Rex ha ha

 

For those of you not familiar with Anzu here is the beast dubbed "the chicken from hell"  3 meters long

 

Another bigger claw this is the REAL Baryonyx thumb claw.  It was collected in January, 1983, by fossil collector William Walker.  Courtsey of the NHM London

 

Ceratosaurus magnicornis courtsey of Kanagawa Prefectural Museum in Yokohama

 

The pterosaur Wukongopterus lii (Tiaojishan Formation (Bathonian/Oxfordian), China

 

 

Ouch! That’s gotta hurt. Broken Diplodocus tail vertebrae

 

 

[Tidgy's Dad]

Incredible! 

Thanks for keeping this going. 

What an amazing world it is and was. 

[HamptonsDoc]

Great stuff!  Thanks for sharing!

[oldtimer]

Incredible fossils shown today.  I love Fridays.

[-Andy-]

Stop it man. My floor is wet enough with drool.

[Bobby Rico]

I am stating to look forward to fossil Fridays . Thanks for posting and some very impressive uk fossils in the mix . Nice illustration work on the chicken form hell .

 

cheers Bobby

[Troodon]

Thanks for the replies and @Haravex for your photos.  Still a lot of good stuff available so plan on marching on to next Friday.

 

@Bobby Rico. Trying to hit all parts of the world and the UK has some beautiful specimens to offer other than the weathered ones you see for sale

 

@-Andy- buy a drool bucket

[JohnBrewer]

I love Fridays!

A genus of abelisaurid theropod dinosaur from the late Cretaceous period of Argentina. It is one of the most complete and informative abelisaurids yet known, described from a nearly complete and articulated skeleton.

 

A nest of theropod dinosaur eggs found in southern Alberta.  Note the pair of eggs beside the paintbrush. Oldman Formation, 75 million yrs old.

 

Holotype of ornithopod Gasparinisaura at Lago Barreales Palaeontology Centre in Patagonia, Argentina

 

Edmontosaurus regalis is a type of hadrosaur commonly found in Alberta. This skull was collected this past field season within 20 minutes from the Royal Tyrrell Museum and is the first relatively complete skull in their collection.  Looks like a bit of work in from of them.

 

This is the beautifully preserved skeleton of the Permian diadectid Orobates. Another really cool animal from the Bromacker quarry in Germany

Good collection of photographs,and a thoroughly enjoyable post.

KUDO'S!

Thanks and my favorite 

[oldtimer]

I love Fridays.  Being from Oklahoma I would have to say my favorite today is the Acrocanthrosaur’s skull.

Super nice photos.  Thanks for posting.

[Bobby Rico]

Fossil Friday delivered again with some incredible fossils for our viewing. I really like the photo of the Tyrannous Daspetosaurus and the man who is showing the incredible scale of the creature. The Royal Belgian institute of Natural Sciences is an fantastic museum and one of my favourites. I think they have about 30 Iguanodons which is pretty special. 

 

Thanks @Troodon for the post

Yutyrannus Huali

 

Compsognathius Longipies

Hopefully 2018 Dinosaur Fridays be equally cool so lets get the new years started 

 

Montanoceratops a partial skull & skeleton! A small ceratopsian from the Late Cretaceous St. Mary River Formation collected by Dr. David Weishampel, thanks to the MOR.   Gotta love how the feet are displayed.

Those are again some really nice fossils posted so far today.

Thanks for posting.  Really makes me drool and wish I had such wonderful specimens.

Can't wait to see what else is posted today. 

[Tate Museum]

Here are a few pix of one single dinosaur...Lee Rex, from discovery to today...

Lance Formation, eastern Wyoming, found by our own jpc and collected by tate Museum crew with a ton of volunteers in 2011.

 

Not many bones on the surface there, but enough to cause us to wonder... "Hey what is in here?"

 

 

After a couple days of five people digging... we have an outline of a concretion and enough bones protruding to ID it as a T rex.  

 

 

If you have an aerial shot of the quarry, include it.  (Pre-drone days).... this was 2011.  That's a shower in the foreground.  It was never used and blew apart in a windstorm (possibly a tornado) that also tipped over two of our three outhouses.

 

 

After 5 weeks of digging with a crew of 20, we found what was to be found, jacketed the 18 foot long concretion and encased it in a box, just like in Jurassic park Number ?? so it couldn't escape. 

 

 

And then found a crane to pick it up and put it on a truck.

 

 

Back at the Tate Museum, we flipped it over to prep it form the bottom... a two-crane project.  

 

 

Tale continues on new post...
