Androgynoceras hybridum Fossil Ammonite, Lower Pliensbachian, Jurassic: Blockley, United Kingdom – 100% Genuine with COA
£48.00
This Androgynoceras hybridum fossil ammonite is an impressive specimen from the Lower Pliensbachian Stage of the Jurassic Period, discovered in Blockley, United Kingdom. Androgynoceras hybridum is an ammonite species recognized for its distinctively coiled shell and well-defined ribbing, providing a fascinating example of ancient marine life from the Pliensbachian period. The ammonite is beautifully preserved in sedimentary rock, offering a glimpse into the Jurassic marine ecosystems that existed over 180 million years ago.
Geological Information:
Geological Stage: Lower Pliensbachian, Jurassic (Approximately 183 to 174 million years ago)
Depositional Environment: During the Lower Pliensbachian period, shallow seas covered much of what is now the United Kingdom, including the area around Blockley. These seas were rich in nutrients and supported a diverse range of marine life, including ammonites like Androgynoceras hybridum. The fossil was preserved in sedimentary deposits, including marl, clay, and limestone, formed by the accumulation of marine organisms over millions of years.
Biozone: This fossil comes from the Lower Pliensbachian biozone, a period marked by the evolution of ammonites and other marine life. The Pliensbachian biozone represents a significant stage in marine biodiversity, with ammonites being one of the dominant groups of marine organisms.
Fossil Features:
Family: Ammonitidae
Super Family: Ammonoidea
Order: Ammonitida
Morphology: The Androgynoceras hybridum ammonite features a distinctively coiled shell with well-defined ribs that run along the length of the whorls. The shell has a smooth texture with pronounced suture lines and strong ribbing, creating a textured appearance.

Jurassic Information
The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
