Geology and Fossil Type Geological Stage: Lower Hauterivian, Cretaceous Depositional Environment: Marine (The Lower Hauterivian was a time of warm shallow seas that supported a diverse range of marine life, including ammonites such as Hemitetagonites crebiscullatum in regions like Madagascar.) Family: Tetragonitidae (A family of ammonites, characterized by their distinct spiral shape and ribbed, often finely detailed shells) Superfamily: Ammonoidea Order: Ammonitida (Ammonites are part of the Cephalopoda class, related to modern squid and octopus) Morphology Features The Hemitetagonites crebiscullatum ammonite features a distinct spiral shape with a smooth yet intricately ribbed surface. The spiral coiling of the shell, along with its well-defined ribbing, provides a unique look at the marine adaptations of this species. The fossil’s suture lines and smooth curvature are indicative of the marine habitat in which it thrived, offering an excellent representation of the ammonite’s role in ancient oceans. Notable Features This ammonite is especially notable for its rarity and the fine detail preserved in its structure.
