Abstract
The present study documents and describes an ovule attached to a fern-like foliage that was collected from Sydney Coalfield, Cape Breton Island, Nova Scotia, Canada. Specifically, the ovule is probably of the Trigonocarpus type and the foliage is assigned to the species Neuropteris (Mixoneura) flexuosa (Sternberg) Crookall, 1959. It is proposed to group this species with Spermatophyta, Gymnospermae, Pteridospermophyta of medullosan affinity.
