Order: Architaenioglossa
Superfamily: Cyclophoroidea
Family: Cyclophoridae (Extinct Tropical Land Snail)
Genus: Hirsuticyclus
Species: Hirsuticyclus canaliculatus

Hirsuticyclus canaliculatus is an extinct species of fossil land snail from the family Cyclophoridae, first described in 2022 from Burmese amber. It is known for its distinctive spirally grooved shell, relatively large size, and flaring peristome interrupted by two canals.

This example is very large, measuring about 14mm-15mm. The amber stone measures about 46mm x 27mm x 12mm. This snail shell is extremely detailed with intricate grooves and patterns.

I'm unsure of the species.

Gerontoformica is an extinct genus of prehistoric "stem-group" ants that lived approximately 100 million years ago during the Cretaceous period. These ants bridge the evolutionary gap between solitary wasps and the social ants seen today.
