Name:
Cardiospermum coloradensis (Balloon Vine)
Age: Eocene
Formation: Green River Formation
Location: Bonanza, Utah
Size: Leaf is 2.5'' long including petiole
This is an excellent specimen of a Cardiospermum coloradensis (Balloon Vine) leaf from the Green River Formation of Utah. Living members of Cardiospermum are herbaceous or woody vines. However, the fossil species appear to represent shrubs rather than vines. This tri-lobed leaf has entire margins which are clearly defined on this specimen. An extremely long petiole (RARE) is still tightly attached to the base of the leaf. The fossil leaf has gorgeous color and contrast and is well presented on the natural plate of shale. This is a beautiful example of this distinctive leaf from the Eocene.
