This image shows an unidentified beetle termite insect fossil found in the Florissant Formation of Teller County, Colorado, USA. The field of view (FOV) is 2 mm. It dates to the Eocene Epoch of the Paleogene Period.
Thanks to Kenny for the image.
UPDATE (2021-02-20): Kenny informs me this might not be a beetle but instead a termite. I have updated the labels in the post.
