RARE PAVLOVIA PAVLOVI Fossil Ammonite – Middle Volgian, Tithonian, Jurassic-Cretaceous Boundary: Russia – Alice Purnell Collection

Description

A rare and striking fossil ammonite of the species Pavlovia pavlovi, collected from the Middle Volgian Substage of the Upper Tithonian, spanning the Jurassic-Cretaceous boundary. This exceptional specimen was sourced from the Iastria River, Siranpaul Region, located in the Polar Urals of Western Siberia, Russia, and originates from the esteemed Alice Purnell Collection.

Pavlovia pavlovi is a well-known species within the Perisphinctoidea superfamily and the Dorsoplanitidae family. These ammonites are renowned for their evolute, discoidal shells with pronounced ribbing and no keels, often exhibiting a high degree of preservation in Siberian localities due to unique sedimentological conditions.

Geological & Scientific Details:

• Scientific Name: Pavlovia pavlovi
• Fossil Type: Ammonite
• Geological Period: Late Jurassic to Early Cretaceous
• Geological Stage: Tithonian (specifically Middle Volgian Substage)
• Location Found: Iastria River, Siranpaul Region, Polar Urals, Western Siberia, Russia
• Order: Ammonitida
• Superfamily: Perisphinctoidea
• Family: Dorsoplanitidae
• Morphological Features: Strongly ribbed, evolute coiling, discoidal form without a keel, typical of late Jurassic northern ammonite faunas
• Biozone Association: Often linked with the Pavlovia and Epivirgatites biozones of the Middle to Upper Volgian
• Depositional Environment: Cold epicontinental sea margin; fine-grained marine sediments in relatively low-energy depositional settings promoting fossil preservation

This ammonite is not only a collector’s gem but also a key reference species in correlating Russian marine stratigraphy with global Jurassic-Cretaceous boundary sections.
