These images show unidentified fossils found in the
Florissant Formation of Teller County, Colorado, USA. The field of view
(FOV) for the top one is 2 mm and it could be a fragment of horsetail plant with predation holes. The second could be a seed or a coprolite and its FOV is 5mm. They date to the Eocene Epoch of the Paleogene Period.
Thanks to Kenny for the images.
