context_page_description: Schmalenseeia is genus of trilobites of uncertain affinity, that lived during the middle Middle to earliest Upper Cambrian. Species assigned to Schmalenseeia have been found in Norway, Sweden, Northern Siberia, Eastern China, Australia, India and the United Kingdom.
context_section_description: The first species of Schmalenseeia to occur in the fossil record, S. acutangula, must have developed from an early species of Burlingia. It is intermediate between the two genera. The affinities of the family Burlingiidae to which Schmalenseeia has been assigned remain uncertain. Schmalenseeia shares many features with Kleptothule, such as a glabella tapering forward and a prominent preglabellar ridge, but a close relationship seems unlikely due to the apparent lack of facial sutures and the much earlier appearance in the fossil record of Kleptothule.
