Trigonocarpus attached to Alethopteris frond.jpg
This Trigonocarpus fossil from St. Clair is an exceedingly rare pairing that includes the compression (fossil) and impression (cast) in matching pieces. If you look very closely you can see there is a short stem connecting the seed to the Alethopteris stem. Finding these connected is VERY rare. Also, if you look closely you can see some sort of structure revealed in the very center of the seed.
