| Fruits resembling the modern woodland herb, Actaea (baneberry, Ranunculaceae) are small bilaterally symmetric follicles bearing around 20 seeds with seed coat with a prominent palisade outer layer. A similar fruit is described from the London Clay. These specimens document evidence of rare herbaceous Ranunulaceae in late Paleocene/early Eocene floras of North Dakota and England, supporting a North Atlantic land bridge connection. |
