Rieppelia heinzfurreri
(Ferrante and Cavin, 2023)

Rieppelia is an extinct genus oflatimeriidcoelacanth fish from theMiddle Triassic ofSwitzerland, in what is nowMonte San Giorgio. It contains a single species,R. heinzfurreri.[1]

Naming

[edit]

The generic name is given in honor of Dr. Olivier Rieppel, who was the first to report the presence of the taxon in the fossil fauna of San Giorgio. The species is named after Dr. Heinz Furrer, who made major contributions to the geological and paleontological research of Switzerland, especially the deposits of the Triassic period.[1]

Description

[edit]

Rieppelia is an unusually short (63 cm) and stout coelacanth, akin to the closely relatedForeyia. Its skull and fins had features reminiscingPaleozoic coelacanths, and a non-functional intracranial joint. Teeth were many, small, pointed and curved.[1]

Habitat

[edit]

Rieppelia lived in shallow lagoons or basins at the western end ofPaleo-Tethys Ocean, and along with related genera was probably anendemism.[1]

Classification

[edit]

Rieppelia is a close relative of TriassiclatimeriiidsForeyia andTicinepomis, and together they are grouped in the subfamilyTicinepomiinae.[1]
