Fossil Type: Ammonite (Extinct Marine Cephalopod)

Species: Zetoceras zetes

Geological Period: Jurassic (~201 to 174 million years ago)

Geological Stage: Lower Pliensbachian (~190 to 183 million years ago)

Location: Hinterriss, Tyrol, Austria

Scale Rule: Squares/Cube = 1cm (See photo for full sizing)

Specimen: What you see is exactly what you’ll receive—the photographed fossil

Authenticity: All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity

Geological and Paleontological Information

Zetoceras zetes is an extinct genus of ammonites, a group of externally-shelled cephalopods that flourished in the Mesozoic oceans. The Lower Pliensbachian marks an important interval in Early Jurassic marine evolution, and ammonites from this stage are key for regional and global biostratigraphic correlation.

  • Phylum: Mollusca
  • Class: Cephalopoda
  • Subclass: Ammonoidea
  • Order: Ammonitida
  • Superfamily: Eoderoceratoidea
  • Family: Dactylioceratidae
  • Genus: Zetoceras
  • Species: zetes
  • Depositional Environment: Shallow marine shelf with calcareous sedimentation; oxygen-rich waters conducive to ammonite proliferation
  • Morphological Features: Moderately involute shell with fine ribbing and prominent whorls; the shell’s complex suture lines and preserved surface features reflect typical early Jurassic ammonoid characteristics
  • Biozone: Associated with the Uptonia jamesoni or Amaltheus margaritatus ammonite zones (depending on stratigraphic context in Austria)
  • Identifier: Described by Mesozoic paleontologists refining the taxonomy of early Jurassic cephalopods in the Alpine region

Why This Fossil is Special

Zetoceras zetes from Hinterriss is a rare and well-documented ammonite species, offering both aesthetic appeal and scientific value. Its preservation within the classic Lower Jurassic deposits of the Northern Calcareous Alps makes it an ideal collector’s piece or teaching specimen.

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.
