This image shows an insect fossil with compound eyes. The fossil was found in the Florissant Formation of Teller County, Colorado, USA. It dates to the Eocene Epoch (56-33.9 million years ago) of the Paleogene Period (66-23 million years ago). Thanks to Kenny for this microscope image. Field of view (FOV) on image is approximately 2 mm.

The second image is a similar fossil but FOV is 1mm.

Close up Isotelus Trilobite Eye

My cousin sent me these images recently after he saw some magnified images of Isotelus trilobite fossil eyes showing the remains of the many lens that made up the eye. We are use to seeing this compound eye more on the Devonian Phacops trilobite fossils found in the area. He took some images under the microscope and you can see some of the lens pattern left on where the eye was.

This fossil dates to the Ordovician Period and was found in Franklin County Kentucky USA.

Thanks to Kenny for the images.
