Saturday, May 12 featured TWO Fossil Hunting expeditions! The FIRST one was PHOTO ONLY - We hiked the Staple Bend Tunnel trail - The Staple Bend Tunnel, about 4 miles (6.4 km) east of Johnstown, Pennsylvania, in a town called Mineral Point, was constructed between 1831 and 1834 for the Allegheny Portage Railroad. Construction began on April 12, 1831.[4] This tunnel, at 901 feet (275 m) in length, was the first railway tunnel constructed in the United States. It is rock bored and stone lined. Finished in June 1833, the Staple Bend tunnel was advertised as the first railroad tunnel in the United States. It was the third tunnel of any kind built in the U.S.; the first two tunnels were for other canals in Pennsylvania. You may NOT collect along here...as it is maintained by the National Park Service... but PHOTOS are welcome! We di dnot see any fossil material here - except for one stone that looked like itmight have shown "fossil raindrops in mud" (pictured) THEN we went for Chinese buffet... and BEHIND that building is one of my old fossil haunts.... Sadly, a MAJOR thunderstorm broke out, but Francis Joseph Serenko III, who was with me, found the brachiopods before the storm hit. THIS deposit has crinoids, bivalves, brachiopods and beautiful Worthenia gastropods. One of the photos shows some of the rock formations - This stone was cut to make the old railway bed.... and drainage culverts - some of which STILL exist. You can see 2 of the drainage culverts, made in the early 1830s. The last 2 photos show the brachiopods Francis found!

From the album: MY FOSSIL Collection - Dpaul7
Multiple Plant Fossil - Neuropteris, Pecopteris, Annularia Plant, other leaves. *Two-sided fossil Ferndale area of Johnstown, Pennsylvania, USA Pennsylvanian - 323.2 -298.9 million years ago Fossils on both sides of specimen. This fine specimen shows two leaflets of Calamites, a member of the Calamitales which belong to the Sphenophytes. Whorls of small leaflets are arranged concentrically around a thin stem and are called Annularia or Asterophyllites. Calamites itself is the name originally given to a stem section, but now applies to the entire plant. These were indicative of humid to wet habitats such as along rivers and lake shores. There appears to be small "branches" of calamites as well. Also on this piece, Neuropteris leaflets - they are usually blunt tipped and are attached by a single stem as opposed by the entire base, like Pecopteris. Also, Neuropteris has an overall heartshape. Fern leaves called Pecopteris grew abundantly in the coal swamps of the Carboniferous Period. These leaves dropped off of a 35 foot fern tree called “Psaronius“, one of the most common Paleozoic types. With its sparse and expansive branches, it resembled the modern day palm tree. It produced as many as 7000 spores on the underside of its leaves. Kingdom: Plantae -
