This video documents a fossil hunting expedition in New Ringgold, Pennsylvania, focusing on the search for unique "pyritized" or "golden" fossils – specimens where the organic material has been replaced by iron pyrite (fool's gold). The host teams up with young paleontologists Dean Rocko and Zach Frink to explore a Middle Devonian (360-375 million years old) marine fossil bed. The video features various fossil discoveries, including trilobites (notably the enrolled Phacops rana, Pennsylvania's state fossil), crinoids, gastropods, and brachiopods. Key highlights include the rare find of a starfish (one of only three ever found in Pennsylvania), the excavation of a pyritized trilobite, and the presentation of a large partial Megalodon tooth. The team discusses ancient environments, geological formations, and demonstrates professional fossil preparation techniques using specialized air tools.
Exploring Pennsylvania's Ancient Past: A Golden Fossil Hunt
0:43 Seeking Golden Fossils: The host travels to New Ringgold, Pennsylvania, to join a fossil dig specifically targeting "pyritized" or "golden" fossils—specimens replaced by iron pyrite, making them appear golden or metallic.
1:52 Meet the Paleontologists: The host is joined by Dean Rocko, a 17-year-old paleontologist specializing in scaphocore scorpions, and Zach Frink, 20, who runs the YouTube channel "Chasing Ghosts."
3:14 Devonian Fossil Bed: The dig takes place in a Middle Devonian site (360-375 million years old), where they search for marine fossils like trilobites, echinoids, and other ancient sea creatures.
5:28 "Enrolled" Trilobites: They frequently find "enrolled" trilobites, particularly Phacops rana (Pennsylvania's state fossil), which rolled up into a ball for defense. Dean theorizes this posture in many fossils indicates a mass dying event from ecological stress like storms.
6:09 Rare Starfish Find: Dean reveals he previously found a starfish at the site, a highly rare discovery as only three such specimens have ever been found in Pennsylvania.
9:48 A Curated Collection: Dean and Zach present the host with a "goodie box" of diverse fossils from various locations, including very primitive Cambrian trilobites (e.g., Wiwaxia, Olenellus gilberti from Utah and Pennsylvania, ~508-512 million years old) and a sea scorpion (Eurypterus remipes, state fossil of New York).
11:34 Fossil Preparation Techniques: Dean demonstrates his method for extracting delicate fossils, using air tools like an air abrasive and air scribe at home for meticulous preparation.
19:46 Insights into a Paleo Lab: Zach provides a tour of his "Chasing Ghosts Paleo Lab" (a backyard shed) and showcases the tools and techniques used in professional fossil preparation, including air scribe, air abrasion, handpicks, and paraloid b72 glue.
21:42 Significant Discoveries: Throughout the dig, the team uncovers various fossils, including pyritized trilobites, a rare complete crinoid, a squid cone (belemnite), and a large partial Megalodon tooth (from South Carolina, ~10-20 million years old).
26:41 Successful Expedition: The day concludes with a successful haul of fossils and a shared appreciation for paleontology and science communication.
27:56 Support the Paleontologists: The video encourages viewers to support Dean's online fossil shop, Familia Fossils on eBay, and Zach's YouTube channel, Chasing Ghosts, for more fossil-related content.
