Dinosaur Fossil Friday

Great pics!

Have you got that Dinosaur Fossil Friday feeling? 

I visited my local Museum this morning for some inspiration.

The Rutland Water Dinosaur, or George. a 15 meter long Cetiosaurus oxoniensis at New Walk Museum in Leicester which is among the most complete sauropod skeletons in the uk, was discovered in June 1968, in the Williamson Cliffe quarry near Little Casterton in Rutland. The skeletal remains have been in the museum since 1975; the majority of the bones in the display are replicas of the originals, which are to fragile to be used. This bone map's colour code is blue is on show in the museum and orange is to delicate for display.

Finally this .rex is not tea total and may have been drinking in the Park because he does seem to be enjoying himself.

While we're on statues, I'd like to add these two statues from the Artis zoo in Amsterdam, the oldest zoo in the Netherlands. The statues are from the 1950s. Very inaccurate by today's standards, but they made a big impact on me when I was a little kid. The stegosaurus posture is just all wrong and it has way too many spikes. And the T. rex has 3 fingers on it's hands and is in the old kangaroo posture.

My contribution, Tidgy versus the dinosaur. 

One of the winners that got a month in the Tortoise Forum Calendar Competition for 2016. 

She also got in into the 2017 and 2018 calendars, but without the dinosaur.

Love the fact that the Topps dinosaur cards are shown muching on hapless humans. In particular, the herbivorous Parasaurolophus seems to have a taste for infants.

 

Cheers.

I visited that too! 

I wonder if we were there at the same time? 

[ynot]

You have outdone Yourself Frank!

I think this is the best "dino friday" so far!

This from our neighbors to the south in the other square state...

 

worth watching.

A T-rex conflagration is a surreal sight!

And he’s eaten far too many trikes!

This theory appeared in a Utah newspaper on August 15, 1920...A stegosaurus with its plates laying horizontally, used for gliding short distances through the air... Wow Dinosaur Fridays is the place to learn something new   

 

 

 

Sinosauropteryx dinosaur from Beijing museum

 

 

 

 Wukongopterus was a flying reptile of a different kind found in Liaoning, China, from the Daohugou Beds, of the Middle or Late Jurassic. It was unusual for having both an elongate neck and a long tail

 

 

 

Synapsids are weird but can be pretty spectacular, like this amazing Cotylorhynchus  at the AMNH

 

 

 

40 million year old fish from Monte Bolca, Italy in the collection Wisbech Museum

 

 

 

This cast of Linheraptor exquisitus is a dromaeosaurid with a backwards pointing pubis bone like a bird

 

 

 

The early bird catches the worm, but Protopteryx is *so* early it still has hands and teeth

 

 

 

The wonderful skull of Cretaceous ornithopod dinosaur Jinzhousaurus, courtesy of NHM dinolab

 

 

 

Yanornis is an extinct genus of fish-eating Early Cretaceous birds. 

 

 

 

[Troodon]

Here’s a coracoid bone from a California condor found in Genessee County, NY. This and other finds show that these birds once had a much wider distribution across North America

 

 

 

Beautifully preserved Baurusuchid from the Bauru Group, late Cretaceous, Brazil

 

 

 

Ogygiocarella is arguably the first trilobite that was scientifically described. Rev. Edward Lhwyd published in 1698 in The Philosophical Transactions of the Royal Society, the oldest scientific journal in the English language. This fossil's discoverer thought it was a flatfish.

 

 

 

Fossilization by pyritization! Chotecops ferdinandi from the Lower Devonian Hunsrück-Schiefer, Germany - one of the very rare occurrences of trilobites preserving appendages

 

 

 

Cavenderichthys - Jurassic Australia, Talbragar Fish Bed.

 

 

 

This most wonderful plesiosaur was found by a fisherman in 2003 and no detailed study has yet to be published. On display at the Somerset Museum.  Hmmm wonder what type of bait he was using 

 

 

 

Croc-line archosaurs like the "Rauisuchian" Batrachotomus were the dominant terrestrial carnivores during the mid Triassic. 

 

 

 

An early whale, Rodhocetus, in Field Museum. ~50m years old

 

 

 

Type skull of the Early Cretaceous polycotylid plesiosaur Edgarosaurus muddi MOR_Montana

 

 

 

Montsechia vidallii  appeared 130 million years ago, it is the first plant with flower.

On the lighter side of Dinosaur Friday

 

 

 

 

Jack Horner recently tweeted : The proof is in the pudding as they say! While wondering in the woods just north of Palomar Mountain in Southern CA, I came across a T. rex chasing a Spinosaurus! I didn’t hang around to witness the outcome, but I think it was well established that back in 2001.

 

 

 

Devil’s Corkscrews” are the coolest trace fossils. Discovered in the 1890s, they’re the remains of a Miocene beaver’s spiral burrow! Paleocastor carved these burrows with their teeth and claws, similar to modern prairie dogs.

It is why I added the link.  Cool critter

[Tidgy's Dad]

Marvelous as usual. 

Thanks, Frank.

[ynot]

Another wonderful selection of fossils, thanks for sharing Frank!

[Bobby Rico]

Frank this is an amazing instalment of fossil Friday. Astrapotheria is very cool and nice beaver burrow . Thank you 

 

  I like add a few  of photos.

 

1.Megatherium from lujan

near Buenos Aires Argentina Natural History Museum London. 

2. This is one of Mrs Rico’s photos a Megalania at the Melbourne Museum. A giant monitor lizard from southern Australia.

3 Petrified Conifer Log Triassic Chinle Formation, Navajo County, Arizona

4.News-Journal, Mansfield, Ohio, October 7, 1927 with clear evidence that the science has moved on. Also you would need a pocket full of garbage bags pick up after your stegosaurus.

Spectacular !

Cannot await next Friday

Good friday!
