Its eye includes roughly 100 ommatidia, that are situated relatively far apart when compared with contemporary compounds eyes, they added.
An worldwide group of researchers made the find while analyzing the fossil of the species known as a trilobite unearthed in Estonia, based on the study printed within the Proceedings from the National Academy of Sciences journal.
A test from the fossil revealed the species likely had poor vision when compared with many modern creatures, however it could still identify approaching predators, researchers stated.
“This could be the earliest illustration of a watch that you’ll be able to find,” stated Professor Brigitte Schoenemann, from the College of Perfume, which conducted the study combined with the Tallinn University of Technology in Estonia.
Scientists have discovered the things they believe may be the earliest eye ever discovered inside a 530-million-year-old fossil.
