DEFOSSICERAS DEFOSSUS Yorkshire Ammonite Fossil – Pliensbachian, Jurassic – North Yorks, United Kingdom – 100% Genuine with COA

Description

This DEFOSSICERAS DEFOSSUS ammonite fossil is a unique specimen from the Pliensbachian stage of the Jurassic period. It was discovered in North Yorks, United Kingdom, a renowned area for its fossil-rich deposits. The DEFOSSICERAS DEFOSSUS is a rare and visually striking ammonite, and its preservation in this fossil is a testament to the marine life that flourished during the early Jurassic

Geological Information:

• Geological Stage: Pliensbachian, Jurassic (Approximately 189 to 183 million years ago)
• Depositional Environment: The Pliensbachian period was characterized by shallow seas and rich marine life. The ammonite was preserved in a marine sedimentary environment, where fine sediments from ancient seas accumulated, allowing for the preservation of delicate marine organisms like ammonites. Fossils from this period, including Defossiceras, provide insight into early Jurassic marine ecosystems. The fossil was found in North Yorks, which has a significant geological history that dates back to the early Jurassic period.
• Biozone: Fossils from the Pliensbachian biozone are crucial for understanding the diversity of life in the early Jurassic seas, a period that was rich in ammonite species and other marine creatures. This fossil helps document the ammonite evolutionary lineage during the early Mesozoic era.

Fossil Features:

• Family: Ammonitidae
• Super Family: Ammonoidea
• Order: Ammonitida
• Morphology: The DEFOSSICERAS DEFOSSUS ammonite features a distinctive ribbed and smooth shell with a moderately coiled structure. The ammonite’s ribs are well-defined, and the shell is slightly compressed, a characteristic feature of this species. The suture lines are visible and offer insight into the ammonite’s evolution. The specimen is well-preserved, allowing the intricate details of the shell to be clearly seen. This ammonite is an excellent example of the Pliensbachian period ammonites and provides valuable insights into Jurassic marine life.
• Zone: The fossil was found in the Pliensbachian zone, which marks an important period in the evolution of ammonites and other marine organisms.
