Description
Undescribed Angiosperm Seed
Late Cretaceous
Judith River Formation
Central Montana, USA
Excellent black nut, 0.6 inches in grey matrix. Unusual.
Here’s a plant fossil occasionally found in the Judith River Formation. It looks sort of like a sunflower seed but the earliest proposed relative of true sunflowers did not appear until the Middle Eocene (30 million years later).
