bowtiemallia
Bowtiemallia is a genus of extinct marine gastropods known from fossil records dating to the Late Triassic to Early Jurassic. It is notable for a small to medium-sized, globose shell featuring a distinctive transverse constriction that yields a bow-tie-shaped cross-section when viewed from the side, a feature that gives the genus its name.
The name Bowtiemallia combines the bow-tie silhouette with the surname Mallia, in honor of paleontologist Maria
As of current revisions, three species are recognized: Bowtiemallia triassica, Bowtiemallia undulata, and Bowtiemallia quadrata. Differences
Fossils have been found in Late Triassic to Early Jurassic rock sequences in parts of Europe and
