Saynoceras verrucosus Ammonite Fossil Tithonian Cretaceous Russia Genuine Certified Specimen

Description

Authentic Saynoceras verrucosus Ammonite Fossil from Russia

This remarkable Saynoceras verrucosus ammonite fossil originates from the Tithonian stage of the Late Jurassic to earliest Cretaceous (approximately 152–145 million years ago) and was discovered in Russia, a region known for producing exceptionally well-preserved ammonites. The specimen offered here is 100% genuine, with the photographs displaying the exact piece you will receive. A Certificate of Authenticity is included, ensuring its scientific and collectible value. The scale shown is 1 cm per square for accurate measurement of the fossil.

Geological Importance – The Tithonian Stage

The Tithonian stage marks the final interval of the Late Jurassic, transitioning into the dawn of the Cretaceous. During this time, marine environments were flourishing, and ammonites such as Saynoceras verrucosus were highly diverse and abundant. They played a crucial role in the oceans as nektonic predators and are today essential tools in stratigraphy, providing biostratigraphic markers that allow geologists to date and correlate sedimentary rocks across different continents. Fossils from this stage are historically important for piecing together evolutionary history during one of the most dynamic geological intervals.

Scientific Classification

• Class: Cephalopoda
• Subclass: Ammonoidea
• Order: Ammonitida
• Superfamily: Perisphinctoidea
• Family: Himalayitidae
• Genus: Saynoceras
• Species: Saynoceras verrucosus

This ammonite belongs to a family that was widespread during the Late Jurassic seas and is characterised by distinctive shell features that make it a recognisable and highly valued fossil among collectors and researchers.

Morphological Features

The shell of Saynoceras verrucosus is notable for its robust, ornamented whorls, displaying strong ribbing and occasional tuberculation that provide a textured surface. Its whorl section is moderately inflated, and the ribs sweep across the flanks before terminating along the ventrolateral margins. These features give the ammonite a sculptured appearance and reflect its adaptation to life as a fast-swimming marine predator. The intricate ribbing patterns and nodular ornamentation are defining traits of this species and make it a visually striking fossil to display.

Paleoenvironment and Ecology

During the Tithonian, Russia was part of an expansive shallow sea system that provided ideal conditions for ammonites to thrive. Saynoceras verrucosus would have lived as a nektonic carnivore, using jet propulsion for mobility while hunting small marine organisms, plankton, and crustaceans. Its wide distribution across the Tethyan realm highlights its evolutionary success and ecological importance. Ammonites such as this specimen provide valuable insights into marine biodiversity, paleoceanography, and environmental changes during the Jurassic-Cretaceous transition.

Collectible and Display Value

This Saynoceras verrucosus ammonite fossil from Russia is both scientifically significant and visually appealing. Its bold ornamentation and distinctive form make it a standout specimen for collectors, educators, or anyone fascinated by natural history. Ammonites are among the most iconic fossils in paleontology, and this specimen represents a direct connection to life that flourished in prehistoric seas over 150 million years ago.

Carefully selected for its authenticity, preservation, and display quality, this fossil is a timeless addition to any collection. Whether for a private enthusiast, educational display, or as a unique natural history gift, this piece embodies the enduring fascination of ammonites and the geological story of our planet.
