FossilSniper posted a topic in Fossil Hunting TripsAbout a month ago, I headed out on two fossil trips to the well-known St. Leon roadcut in Indiana. I was hunting in the Liberty formation (late Ordovician) with the sole goal of finding some nice trilobites (which I definitely achieved!). Along with multiple rare trilobites, I was able to find some excellent examples of other fossils. The spoils were totally awesome, and I am itching to go back. I hope you enjoy. Best for last.
Hello, Anyone have any info on trilobites with eyes located on the hypostoma. I have an old textbook (1935!) that states "A few trilobites appear to have lacked eyes, and in some two small compound eyes are present on the ventral hypostoma." No other info is provided!!!!! I would like to read more about this. Thanks, Tim
