The fossilized shells of Ammonites are typically spiral-shaped, very much like that of the Nautilus. However, around 170 million years ago, these squid-like creatures began to build their shells in exotic, highly variable shapes. The species pictured here is Ancyloceras vandenheckii, which is typically found in Morocco. However, heteromorph ammonites are...

Belemnite is the common name applied to an extinct order (Belemnoida) of mollusks belonging to the cephalopod class. Modern cephalopods include the squid, octopus, and pearly Nautilus. The belemnoid animal was most closely related to the squid as it had an internal shell covered by a leathery skin, tentacles that...

Baculites ("walking stick rock") is an extinct genus of cephalopods with a nearly straight shell, included in the heteromorph ammonites. The genus, which lived worldwide throughout most of the Late Cretaceous, was named by Lamarck in 1799. Weight: 35.3 grams, Dimensions: 1 x .5 x 3.25 inches

Ferns are a very ancient family of plants. They predate the beginning of the Mesozoic era, 360 million years ago. By as early as the Triassic period, evidence of ferns related to several modern families appeared. Most modern ferns are leafy plants which grow in moist areas under forest canopy,...

Trilobites, an early arthropod relative of spiders, horseshoe crabs, and scorpions, preserved in this level of detail only occurred as a result of very sudden underwater landslides called turbidite sequences, which ravaged the early earth when the continents were still very much on the move. The contorted body positions of...

The fossilized shells of Ammonites are typically spiral-shaped, very much like that of the Nautilus. However, around 170 million years ago, these squid-like creatures began to build their shells in exotic, highly variable shapes. This specific ammonite is unpolished, revealing its natural coloring. *Stock photo is shown, similar piece will be...

A stunning clustered plate of Orthoceras fossils in sea-bed matrix. The orthoceras mollusk lived in abundance during the Paleozoic Era, some 250 to 750 million years ago. Orthoceras is a member of the class Cephalopoda and is closely related to the extinct giant Cephalopod and present-day chambered nautilus. Orthoceras ("straight...

Mosasaurs are an extinct group of large marine reptiles. Their first fossil remains were discovered in a limestone quarry at Maastricht on the Meuse in 1764. Mosasaurs probably evolved from an extinct group of aquatic lizards known as aigialosaurs in the Early Cretaceous. During the last 20 million years of...

Brittle stars or ophiuroids are echinoderms in the class Ophiuroidea closely related to starfish. They crawl across the sea floor using their flexible arms for locomotion. The most famous Jurassic deposit in the world, is found in the Solnhofen, and Eichstatt of Germany. Limestone that make up this formation were...
