Laudonia is an extinct genus of trilobites that lived during the early part of the Botomian stage, [1] which lasted from approximately 524 to 518.5 million years ago. This faunal stage was part of the Cambrian Period. There are currently two named species assigned to it.
Distribution
- L. bispinata has been collected from the Early Cambrian of Alberta ( Lower Olenellus zone, Mural Formation, Mumm Peak Section, immediately west of Mumm Peak and north of Mount Robson Provincial Park, near Mural Glacier) and of British Columbia (Cinnamon Peak-Whitehorn Mtn. Section: Dyeran) Canada. [4])
- L. amputata is found in the Early Cambrian of Alberta ( Lower Olenellus zone, Mural Formation, Mumm Peak Section, immediately west of Mumm Peak and north of Mount Robson Provincial Park, near Mural Glacier). [4]
- Laudonia sp. is mentioned from the Lower Cambrian of the Caborca Region, Mexico (Puerto Blanco Formation, Cerro Rajon). [5]
