Mamsetia manunis is an extinct animal that hails from the late Ediacaran. Estimated to be about 565 million years old, M. manunis is identified as a cnidarian polyp, and represents some of the earliest known evidence for muscle tissue in an animal. Its fossil was discovered in 2014 from Newfoundland in eastern Canada, and formally described in 2024 as a cnidarian staurozoan based on examination of its overall morphology and structure.[1]
Discovery and name
[edit]The now holotype fossil of Mamsetia was originally the paratype fossil for Haootia from the Trepassey Formation of Green Island, Bonavista Peninsula in Newfoundland. But with the recent 2024 paper placing Haootia in the staurozoa class, it was discovered that the paratype had enough differences in its morphology to that of Haootia, that a new species was erected.
The generic name Mamsetia is derived from the Beothuk word Mamset, meaning "living". The specific name manunis is derived from the Beothuk word Manune or Manume, meaning "pitcher/cup", relating to the cup-like shape of the body.
Description
[edit]Mamsetia manunis is the second animal that has been discovered which consists of bundles of fibres that have been identified as muscles, similar to Haootia. The entire body is in a broadly four-fold symmetrical arrangement, thus the overall body organisation and muscle fibres conforms to the key features of modern staurozoan cnidarians. The fibres, which are similar in pattern to parallelly arranged muscle fibres, extend laterally across the body, linking adjacent corners. The fibres extend beyond each corner to form 4 elongate branches, which divide into smaller dichotomous branches. Smaller branches also arise from the lateral margins of the quadrate body, and also form dichotomously branched fibres. Unlike Haootia, which has 8 primary branches and an open calyx, Mamsetia on bears 4 primary branches and a closed calyx.[1]
