Lygodium kaulfussii, Cardiospermum coloradensis
Age: Eocene
Formation: Green River Formation
Location: Bonanza, Utah
Size: Plate is 5.4" X 8.9"
This is a very unique specimen of Lygodium kaulfussii (Climbing Fern) and Cardiospermum coloradensis (Balloon Vine) from the Green River Formation. The Lygodium kaulfussii (left) has long, finger-like lobes intact. The unusual venation is very easily seen. Living representatives of this plant are true climbers. On the right is a fine specimen of Cardiospermum coloradensis. This interesting lobed leaf is quite distinct in appearance. The fossil leaves have great detail and wonderful natural color and contrast. The plants are nicely spaced on the rectangular plate of matrix. This is an extremely unusual association of two very uncommon leaves from the Eocene.
