Anabarites is a problematic lower Cambrian genus, and is one of the small shelly fossils. It was abundant in the early Tommotian and is also found in the Nemakit-Daldynian.[1] The fossils represent the triradially symmetrical mineralised tube in which the organism dwelt; it was sedentary.[2] It is named after the Anabar region in Yakutia, Russia; its name does not imply 'heavy'.[3]
