The week goes by fast so here is another rendition of Dinosaur Fossil Friday

 

It's a mom and baby Plotosaurus from ucmpberkeley! These were the most ichthyosaur-like mosasaurs

 

 

 

Before cutting bones for histology research, casts of the originals are made for future researchers. At U of T Palaeo they use Smooth-On materials which help cut the cast curing time down to a half hour

 

 

At an Alberta dig site, teeth and skull material is being retrieved from the Tyrannosaur Daspletosaurus

 

 

 

From Alberta- partial hadrosaur egg with embryonic bone inside

 

 

Undescribed sauropod skeleton from the Sahara Desert of Niger NHM London Is it Jobaria? Or something else?

 

 

 

An undesribed jaw from a hadrosauroid dinosaur found from the late Cretaceous of Shanxi, China

 

 

 

Holotype and only known skeleton of the herbivore Parksosaurus from Late Cretaceous of Alberta

 

 

 

One of only 5 specimens in the world of the extinct curly tailed lizard Leiocephalus herminier

 

 

 

Tully Monster in the fossils of LA county museum collection

Photo from the field: skull of a Dimetrodon, “King of the Texas Red Beds. It’s a baby! A little sail-back, not much larger than an iguana . . . or a poodle puppy

 

 

An archegosaur nicknamed “Happy Puppy” courtesy of HMNS. Early Permian amphibian

 

 

 

Although it's fairly common to find shark teeth, it's a little less so to find cartilage preserved with it! a beautiful specimen (Squalicorax kaupi of the Cretaceous Niobrara formation) at the Sternberg Museum

 

 

 

An invertebrate, an incredibly preserved Solnhofen cephalopod

 

 

 

A baby Ceratopsian dinosaur (Centrosaurus apertus) jaw from the McPheeters bonebed, Oldman Fm, Alberta

 

 

 

a dorsal fin spine from the ancient shark Ctenacanthus. This fossil was discovered in the Devonian Cleveland Shale and is 358,000,000 years old!  The second image (Hybodus, a Permian relative) shows how these spines projected out of the back!

 

 

 

Protoceratops Dinosaur egg, Mongolia

 

 

 

520 MYO euarthropod from China, Super cool

 

 

 

Hesperocyon paterculus was the world’s earliest dog. It lived 42-31 million years ago in dens, which it dug into the ground. It’s diet? Other small mammal

 

 

 

The holotype of Megatylopus primaevus at at UTexas a North American Camel

 

 

 

A little crocodilian with skin from the Green River

 

 

 

[Troodon]

Seven tiny brittlestars, Aspidura loricata, from the Triassic upper Muschelkalk Fm. of Gundelsheim in SW Germany

 

 

 

Stegosaurus plate and tail spike from the fie

 

 

 

Ammonites Aegoceras (Aegoceras) lataecosta. From BRLSI geological collection - these are used as the logo of Bath Geology Society

 

 

 

Mongolian dinosaurs footprints. Theropod (top left), sauropod (top right), and two hadrosaurs (bottom)

 

 

 

A Coelophysis quarry block under preparation on exhibit at Ghost Ranch

 

 

 

There is much to be learned from Cope's Elasmosaurus.  We are constantly learning with new discoveries and knowledge.

 

 

 

Fossil fish triplets from the devonian of Orkney.

 

 

 

This Mioplosus died 33-55 MYA probably because of not being able to swallow too large another fish. Both predator and prey became fossilized

 

 

Hand talon of the raptor Sinornithosaurus. Over the bone, the nail covering is preserved – thin and sharp

 

 

 

Triassic cynodont from the Manda beds of Tanzania

 

 

 

Here is part of the skull of a juvenile Gorgosaurus, as stored in the ROM toronto collections

 

 

 

The world's largest-known marine reptile, Shonisaurus sikanniensis, was found in BritishColumbia

 

 

 

 

[Troodon]

 

A little T-rex Movie nostaliga

 

 

 

 

 

 

 

 

Finally more evidence that Mr Rex is still around.  I do have a Certificate of Authenticity with the photo.

Splendid! 

I wish i could sleep now, until it's Friday again.

I won't sleep tonight now!

Quick... before this gets hijacked by comic books.  

Here is the Tate geological Museum's contribution to Dinosaur Fossil Friday

 

This is a stereophoto of an anyklosaurian osteoderm.  We don't find many of these.  It was found last summer in a bone bed next to a ceratopsian vertebra and a hadrosaur vert.  If you cross your eyes and let the two center images come together it will pop out at you in 3D.  The missing corner in the upper left is what we call the tool mark of discovery.  We like to avoid these, but hey.... 

 

The staff here is cataloging fossils today and this looked like a great specimen to share with you folks... freshly cataloged as Tate v3910. 

Lance Formation, Niobrara County, Wyoming.  It is about 6 inches (15 cm) long.  

[Tate Museum]

And introducing the latest Tate Museum specimen...

Tate v3911, an ornithomimid? metatarsal.  

I put a question mark on my ID because it is only half the size of the Struthiomimius' metatarsals on display here.

Or you could go with the original (the writing was a bit risqué, especially for 1924):

Thanks @Troodon Frank and off course everyone else for the very enjoyable  Dinosaurs Fossils Friday . The euarthropod from China, is really something special. 

 

Cheers Bobby

Troodon... The Tate Museum folks are not well versed on Lance/Hell Creek Oviraptors, but this thing certainly has a theropod look to it, so maybe.

Wow the stereo thing actually worked! It looks like it’s just sitting on a table in front of me.

Like to thank everyone that contributed to last weeks Dinosaur Friday @Tate Museum  @doushantuo @Bobby Rico @Kane @Sagebrush Steve

[Troodon]

Will start off this week with a  "did you know subject"

 

Did you know 

That we are closer to the time of the T-rex than T-rex was to the time of the Stegosaurus, Allosaurus and Diplodocus 

 

 

 

A specimen of Beothikus mistakensis, an Ediacaran rangeomorph organism, from Spaniard's Bay, Newfoundland. This is what life looked like, on the deep sea floor, 570 million years ago

 

 

An AMAZING specimen of the pterosaur Anhanguera from Brazil's Early Cretaceous Santana Formation! Currently on display CMNH, this remarkable fossil is preserved in 3D, with no crushing of the delicate, hollow bones.

 

 

very cool comparison between giant azhdarchid pterosaurs and a large male giraffe (yes, they can get this big!). Pterosaurs are Arambourgiania (left) and Hatzegopteryx - slender and robust takes on the giant azhdarchid bauplan.

 

Staying on the pterosaur theme

Here is a vertebra belonging to Quetzalcoatlus, the largest known flying pterosaur from the late Cretaceous period. Or possibly a lost teddy bear from the 1800s. Not sure. (Dinosaur Provincial Park, Alberta)

RBINS museum, here’s the gigantic Hainosaurus bernardi, also from the Maastrichtian of Cipl

 

[Troodon]

Oligoserranoides budensis is a small perch-like marine fish from the Carpathian Mountains of Poland. Oligocene, 34-23 million years old. Possibly closely related to snappers

 

 

Here's a dorsal (birds-eye) view of Cyomodus, an early reptile from the Jurrasic of Germany

 

 

The oldest record of vertebrate life on land are fossilised tetrapod footprints on Valentia Island, Ireland. A primitive amphibian like animal left its footprints on a muddy shoreline when Ireland was a swampy area near the equator about 385 million y/a

 

 

Look at this tiny ichthyosaur embryo! This was probably pushed out of the mother during fossilization. Amazing specimen

 

 

 

Complete skeleton of the small-bodied sea turtle Rhinochelys nammourensis from the Cretaceous of Lebanon.

 

 

Mazon Creek Lagerstätte, USA, a Carboniferous (300 million year old) fossil this spider which currently is undescribed

 

 

This cutie is Elonichthys, a ~310 million year old bony fish also from the Mazon Creek of Illinois.

 

 

Ammonite from Canada with Mosasaur bite marks. This specimen is also preserved with shiny ammolite (gem preserved nacre), which features a web of cracks between the bite marks

 

 

A 47 million year old extinct rodent preserved almost perfectly at the Messel Pits, Germany

 

 

[Troodon]

Here is the skull of the holotype of Thililua longicollis, a strange polycotylid plesiosaurian from the Turonian of Morocco. Soon to be published

 

 

Tchadailurus adei - A Sabercat from the Miocene of Chad. Le Museum new Macahirodont from the Sahelanthropus bearing strata

 

 

Mioplosus labracoides, believed to have been a voracious freshwater predator.  It is related to the modern-day Zander (pike-perch) and comes from the famous Green River Shales of Wyoming. Eocene, 57 million years old.

 

 

Osteolepis macrolepidotus is a freshwater rhipidistian, having a number of features in common with tetrapods (land-dwelling vertebrates). Found in the Sandwick fish beds, Orkney - Scotland. Middle Devonian, 387-359 million years old.

 

 

Paleoniscoids were a group of extinct fishes with heterocercal tails and diamond-shaped ganoid scales. Pteronisculus cicatrosus (~7.1cm) is a marine fish from the Ambilobe region in northern Madagascar, Lower Triassic 240 million years old

 

 

A Panthera leo atrox (American lion) skull from the Fossil Collection at the Museum of Nature

 

 

 

Femur of the giant sauropod Alamosaurus, from Big Bend NP, Texas...hey they grow everything big in Texas

 

 

Bones of the Texas pterosaur, Quetzalcoatlus

 

 

From the Texas Vertebrate Paleontology Collections- holotype of Belodon superciliosus, Cope 1893

 

 

Complete hindlimb of the Jurassic Dinosaur Dilophosaurus at the vert paleo collections in Austin

 

 

Hygophum sp. are small (~3.5 cm) mesopelagic fish of the family Myctophidae (lantern fish). Myctophids are among the most numerous fish in the ocean. This fossil is from Marecchia, Italy and is relatively recent, early Pliocene 5-7 million years old

 

 

Shed teeth from a Gorgosaurus (a tyrannosaur), collected in a dinosaur bonebed in SW Saskatchewan, Canada
