Question: The Cardigan Pluton was built during what Middle Devonian period?
Sentence (from "Aneurophyton"): While a number of species have been described in the paleobotanical literature, the genus likely only contains two well-circumscribed species, "A. germanicum" and "A. doui", and possibly a third species, "A. olnense", from Fammenian outcrops in Belgium.
Relevant evidence: No
