Hi, @inkar-arzah, Cenozoic fossils are found in specific places – this holds true for Mesozoic and Paleozoic fossils as well. There are Cenozoic fossil bearing rocks but also many shales and more brittle rock that sometimes just look like soil. Does this answer your question? Maybe @imagallanes has extra information to add?

@inkar-arzah At first glance, this looks like a fragment of a worn horn coral (Grewingkia) to me.
