Fritzolenellus is an extinctgenus from a well-known class of fossil marine arthropods, the trilobites, with three known species.[2] It lived during the early part of the Botomian stage, which lasted from approximately 524 to 518.5 million years ago. This faunal stage was part of the Cambrian Period. Fritzolenellus occurred in parts of the paleocontinentLaurentia in what are now Northwestern Canada, Northwestern Scotland, and North-Greenland.

Temporal range: late Lower Cambrian (Lower Olenellus-zone) 524–518.5 Ma
F. truemani (Walcott, 1913), (type), synonym Olenellus truemani[1][2]
F. lapworthi (Peach & Horne, 1892), synonym Olenellus lapworthi[2][3]
F. reticulatus (Peach, 1894), synonym Olenellus reticulatus[2][3]

The generic name is a combination of the genus Olenellus, to which these species were originally assigned,[4][5] and a reference to William Henry Fritz (1928-2009), a paleontologist who worked on olenelloid trilobites. The species names have the following derivation.
reticulatus (Latin) refers to the coarsely netted exoskeleton.
Distributionedit
F. truemani was collected in the Lower Cambrian (lower Olenellus-zone) of Alberta, Canada (Mural Formation, in the talus slope immediately west of Mumm Peak, from the middle Mural Formation, 125 m above the base of that formation, just north of the Mount Robson Provincial Park boundary). It is also known from North-Greenland (Henson Gletscher Formation).[6]
F. lapworthi occurs in the Lower Cambrian (lower Olenellus-zone) of Scotland (Allt nan Righrion,[4] Meall a ‘Ghiubhais, Loch Awe),[3] and from the middle Dryeran of Northeastern Greenland (Upper Bastion Formation at Albert Heim Bjerge).[7]
F. reticulatus is found in the Lower Cambrian (Lower Olenellus-zone) of Scotland (Meall a ‘Ghiubhais,[4] Allt nan Righrion, Loch Awe).[3][2]
