The tree fern genus Tempskya, known from worldwide Cretaceous deposits, was first reported from a North Carolina site in the February 1970 issue of the Lapidary Journal (article reprinted in February 1977 issue). A follow-up article on additional finds appeared in the January 1978 Lapidary Journal. The collecting site is now inaccessible and overgrown. Cut and polished trunk slabs show multiple roughly oval-shaped structures that are stems, surrounded by a mass of tiny roughly circular structures that are roots. Stems often have knobby projections that are budding leaf petioles, and free leaf petioles can appear in single or multiple horseshoe-shaped structures as the grow towards the trunk's surface. Photos show a collection of 31 of 40+ North Carolina slab specimens.
