Fossils

The belemnites are a monophyletic group of superorder status, called the Belemnoidea. There are four orders . The belemnites evolved from nautiloids, which are the basal group of cephalopods. Well-formed belemnite guards can be found in rocks dating from the Mississippian (or Lower Carboniferous).

The belemnites on offer are of Cylindroteuthis and Pachyteuthis genus.  They date from the Callovian era.  In the geologic timescale, the Callovian is an age and stage in the Middle Jurassic and It is the last stage of the Middle Jurassic, following the Bathonian and preceding the Oxfordian.  They were found in Mikhailov, Ryazan region. Russia.

Cylindroteuthis is a common find from several Jurassic formations.  The most commonly preserved part of the animal is its guard, or rostrum, which was composed of calcite. The guard housed a phragmacone, which allowed Cylindroteuthis to maintain buoyancy in water. Some better-preserved specimens have features similar to modern squid, such as ten arm-like appendages and an ink sac, intact.

Pachyteuthis is a genus of belemnite that lived from the Early Jurassic to the Early Cretaceous and has been found in Asia, Europe and North America. The type species is P. densus.

Name: Cylindroteuthis
Age: Middle Jurassic
Location: Ryazan region, Russia

You will receive 1 of the pictured Ammonite halves.  These are perfectly fossilized and highly polished natural Ammonites from Morocco.  They are a perfect for gift for a new fossil collector. Ammonites are perhaps the most widely known fossil, possessing the typically ribbed spiral-form shell. These creatures lived in the seas between 240 - 65 million years ago, when they became extinct along with the dinosaurs. They belong to a group of predators known as cephalopods, which includes their living relatives the octopus, squid, cuttlefish and nautilus.  These are perfect if you make jewelry and similar crafts or as a fossil collection item.  They average between 33and 38 mm in length.

This is a fossilized, highly polished natural Ammonite in brown marble from Morocco.  it measures 61x61 mm (2.4x2.4 in) and weighs  69 grams (2.4 oz).  Ammonites are perhaps the most widely known fossil, possessing the typically ribbed spiral-form shell. These creatures lived in the seas between 240 - 65 million years ago, and became extinct along with the dinosaurs. They belong to a group of predators known as cephalopods, which includes their living relatives the octopus, squid, cuttlefish and nautilus. 

This specimen is great as teaching tools in the home or in the classroom, or as gifts.  It can also be used for science projects and other types craft displays.

This is a nice fossilized, highly polished natural Orthoceras from Morocco which is perfect for gift giving to a new fossil collector.  This specimen weighs 1,580 grams.

Orthoceras ("straight horn") is a genus of extinct cephalopod. This genus is sometimes called Orthoceratites. Note it is sometimes misspelled as Orthocera, Orthocerus or Orthoceros.  Orthoceras are common fossils and have been found on many continents, including the Americas, Africa, Europe and Asia. They are dated to the lower Ordovician to Triassic ages (500 to 190 millions years ago).  

They belong to a group of predators known as cephalopods, which includes their living relatives the octopus, squid, cuttlefish and nautilus. These are priced as an entry level fossil. Have a look as we are constantly adding more to our selection.
