Fossil Brittle Stars

The Fossils of complete brittle stars (more commonly called starfish) are rarely found. Brittle stars are marine invertebrates that dwell in all the oceans around the world. Because they have thin exoskeletons they are less likely to fossilize that other

This Moroccan brittle star fossil dates back to the Ordovician Period, over 450 million years ago, and clearly shows the brittle star's five "arms."

 These brittle stars are some of the most beautiful and artistic of the fossils waiting to be discovered.  Their form, coupled with their incredible shapes make them a true piece of natural art.

Spinosaurus

One of the most bizarre dinosaurs of all time is Spinosaurus.  This incredible creature looked like no other dinosaur.  It was the largest carnivorous dinosaur that ever walked the earth.

These dinosaurs have an incredible selection of weapons.  It had fascinating teeth that were cone shaped rather than the typical blade shape of most other meat eating dinosaurs.

They also had incredible claws meant to terrorize their prey.  Their hand claws were shaped like sickles and could tear through the flesh of their next meal.

They were also also equipped with large foot claws to hold and tear at their food.

Amazing Articulated Mosasaur Skull

This is one of those incredible times where nature conspires to create a truly incredible piece of art and science.  This is an amazingly well preserved skull of a mosasaur called platecarpus.  This specimen was found int he Sahara Desert region of Northern Africa.

When this skull was pulled from the ground we knew it was something different about it.  As it was taken into the lab and the matrix began to be removed we realized what a true treasure this was.  It was an amazing skull.

This skull was incredibly well preserved and complete.  It was well preserved and articulated enough that you could see where every part of the skull went together and how everything was connected.

As the remainder of the matrix was removed it became clear that this was a stunning mosasaur fossil with nearly everything in place and well preserved.

This mosasaur skull was so incredible just as it had been displayed by nature that is seemed a crime to take it apart and assemble it as a 3-D skull for display.

 It was at this point we determined the best scenario for this amazing creature would be to clean off the matrix and mount and display it in its natural state.

Dyrosaurus, the bizarre Marine Crocodile

Dyrosaurus is a bizarre marine crocodile from the Eocene period.  It lived mainly in Northern Africa.

Dyrosaurus Fossil from Fossil Shack

These strange crocodiles are best known for their long narrow snouts and large jaw muscle attachments.

Dyrosaurus prepared by Fossil Shack

These amazing crocodile fossils are often found in the same locations a mosasaur and shark remains, leading scientists to believe that they existed together for millions of years.

Sea Scorpions

Sea Scorpions or Eurypterids are an amazing group of ancient animals.  They ruled the seas at the same time as the trilobites.  These amazing creatures were related to both trilobites and modern scorpions.

This amazing eurypterid can be found at http://www.fossilshack.com/eurypterids--sea-scorpions.html

These creatures prowled the ocean bottoms in search of prey.  They possessed many appendages similar to those of scorpions but also has special adaptations for life in the ocean.

This piece collected by www.fossilshack.com has three complete sea scorpions and many partials on the same stone.

Here is a very small eurypterid with nearly complete appendages.  This specimen was collected by www.fossilshack.com . 


Most Eurypterids inhabited very shallow brackish and fresh water environments, and some may have been able to walk on land. Their bodies were made of many segments and joints. Most Eurypterids were under 10" in length, but some genera, such as Pterygotus and Jaekelopterus could reach lengths of over 7 feet, and may have been the largest arthropods to ever live.

Check out more Eurypterids at www.fossilshack.com .

Tracks Across Time

Sometimes we get more information from things other than the fossilized bones of ancient animals.  Tracks are one of these amazing resources.  We can learn from fossilized tracks just how muscles and skin on the feet looked.  We can also learn, as is the case at Johnson's farm in Utah that dinosaurs could swim, we see where they sat on their haunches and can see how their running stride differed from their walking gait.

These tracks are an amazing scientific resource and a tremendous collector piece.

Many people do not know that dinosaur tracks are names, but not for the dinosaur that possible made them.  They are described, just like any fossil, by their individual attributes.  These tracks are called Grallator and were possibly made by Coelophysis ot Dilophosaurus.

Mammoth Teeth from the deep

The woolly mammoth was a species of mammoth, the common name for the extinct elephant genus Mammuthus. The woolly mammoth was one of the last in a line of mammoth species, beginning with Mammuthus subplanifrons in the early Pliocene.

Scientific name: Mammuthus primigenius

These teeth are commonly found by fishermen at the bottom of the North Sea.  They are caught in their nets and brought to the surface.  These teeth must then be stabilized so they do not crumble.
