Description
This listing features a RARE 5″ Fossil Ammonite – Podagrossites pseudogrunnia, an exceptionally preserved and scientifically significant ammonite from the Upper Toarcian Stage of the Early Jurassic, sourced from the renowned fossil locality of Roufflac, France. This genus is relatively uncommon and prized among collectors of Toarcian ammonites.
As with all of our fossils, this is a 100% genuine specimen that has been carefully hand-selected and comes with a Certificate of Authenticity. The fossil in the photographs is the exact one you will receive. Please refer to the scale image (each square/cube = 1 cm) for full measurements.
Fossil Overview:
- Species: Podagrossites pseudogrunnia
- Common Name: Fossil Ammonite
- Geological Period: Jurassic
- Stage: Upper Toarcian (~181 – 174 million years ago)
- Location: Roufflac, France
- Size: Approx. 5 inches (12.7 cm)
- Preservation: Fine, detailed suture lines and shell features
Geological & Depositional Environment:
The Upper Toarcian deposits of Roufflac were formed in a warm, shallow marine setting along the northern margin of the Tethys Ocean during the Early Jurassic. These layers are rich in organic material and calcareous sediments, providing ideal conditions for fossilisation of marine organisms.
The presence of Podagrossites in these deposits is significant for biostratigraphic correlation, helping to define specific ammonite zones of the Toarcian.
Taxonomy & Classification:
- Phylum: Mollusca
- Class: Cephalopoda
- Order: Ammonitida
- Superfamily: Hildoceratoidea
- Family: Hildoceratidae
- Genus: Podagrossites
- Species: pseudogrunnia
Morphological Features:
Podagrossites pseudogrunnia is notable for:
- Strongly involute shell with narrow umbilicus
- Finely ribbed flanks with bifurcating ribs
- Rounded ventral area with sharp suture patterns
- Compressed whorl section
These features suggest an active nektonic lifestyle, capable of agile movement in the water column.
Notable Aspects:
- Rare genus not commonly offered in the fossil trade
- Highly collectible due to its scarcity and clear biostratigraphic utility
- From a classic Toarcian ammonite site in France
