| This specimen features a beautiful and interesting chalcedony snail of the species Hippochrenes volgensis from the Paleocene of the Saratov region (Russia). The piece also contains several fossil tower snails of the genus Turritella. In fact, fossil snails from this locality are often identified as this species, although specimens of the genus Turritella appear to be more common at this site than Hippochrenes volgensis. The Hippochrenes volgensis measures approximately 61 mm in length. A distinctive feature of this locality is the preservation of the gastropods as chalcedony pseudomorphs, where the original internal molds have been mostly replaced by chalcedony. The chalcedony also exhibits strong luminescence under UV light, adding to the aesthetic appeal of the specimens. It is indeed an unusual and particularly decorative type of preservation. | |||
