Dendromaia unamakiensis n. gen. n. sp.
Dendromaia unamakiensis n. gen. n. sp. Maddin et al. 2020 synapsid Holotype: The larger of two varanopid individuals preserved in specimen NSM017GF020.001 (Nova Scotia Museum) was discovered by B. Hebert in the lithified infill of a lycopsid stump. Paratype: A small varanopid individual was preserved alongside the large individual in NSM017GF020.001. The genus name has been derived from the Greek word dendron meaning tree and maia meaning caring mother because the animals were discovered in a lithified stump showing proposed parental care behaviour. Species name is after the Mi’kmaq name for Cape Breton Island, where the specimen was found.
