Using the Lock Haven rocks, we can travel back to the Devonian Period, around 400 million years ago. At this time period, Pennsylvania (and most of the east coast of the US) was covered by shallow seas that were VERY different than the seas off the coast of New Jersey and New York today.
When was Pennsylvania under the ocean?
roughly six to four hundred million years ago
Are you ready to take a trip down the Geological Memory Lane to a time when Pennsylvania was not the Pennsylvania we know today? If we stroll back roughly six to four hundred million years ago, Pennsylvania was mostly under marine waters of the Iapetus Ocean, catching sediments over time.
Was Pennsylvania Once underwater?
The geologic column of Pennsylvania spans from the Precambrian to Quaternary. During the early part of the Paleozoic, Pennsylvania was submerged by a warm, shallow sea. This sea would come to be inhabited by creatures like brachiopods, bryozoans, crinoids, graptolites, and trilobites.
Did Pennsylvania have dinosaurs?
A particularly rich source of footprints and track marks has been, of all places, the battlegrounds of Gettysburg in southern Pennsylvania, which were populated by various chicken-sized dinosaurs over 200 million years ago.
What fossils were found in Pennsylvania?
Pennsylvania’s state fossil is of an organism known as Phacops rana, a type of trilobite. Trilobites are an extinct category of joint-legged animals (Arthropods) related to crabs, lobsters, shrimps, spiders, and insects. Trilobites are among the most complex of all the animals that ever existed without backbones.
Which dinosaurs lived in Pittsburgh?
Other species such as ostrich dinosaurs, Dilophosaurus, small plant-eating dinosaurs, and relatives of Coelophysis and Velociraptors likely roamed the region. Eastern North America also has a rich record of prehistoric marine reptiles, like the giant, carnivorous crocodile Deinosuchus.
What created the mountains in Pennsylvania?
The varied geology of Pennsylvania is representative of deep geologic times and events — when geologic plates collided and formed mountains, when the land surface was under water or ice, and even during relatively quiet times.
Is Pennsylvania on a tectonic plate?
Pennsylvania lies in the middle of the North American plate. The eastern edge of the plate is found at the mid-oceanic ridge in the Atlantic Ocean, so we have no plate boundaries in sight.
Why is PA so rocky?
A majority of the rocks in Pennsylvania exposed at the surface are sedimentary and were deposited during the Paleozoic Era. Almost all of the metamorphic and igneous rocks are confined to the southeast portion of the state.
What town was flooded in PA?
The South Fork Dam in Pennsylvania collapses on May 31, 1889, causing the Johnstown Flood, killing more than 2,200 people. Johnstown is 60 miles east of Pittsburgh in a valley near the Allegheny, Little Conemaugh and Stony Creek Rivers.
Was there dinosaurs in Philadelphia?
According to paleontologist Jason Poole, the evidence of Pennsylvania’s dinosaurs comes not from skeletal remains, but from fossilized footprints. Poole is the Dinosaur Hall coordinator at the Academy of Natural Sciences of Drexel University in Philadelphia. He answered our questions via email (links have been added):

Are the dinosaurs at Carnegie real?

What is a dinosaur with 500 teeth?
Nigersaurus had a delicate skull and an extremely wide mouth lined with teeth especially adapted for browsing plants close to the ground. This bizarre, long-necked dinosaur is characterized by its unusually broad, straight-edged muzzle tipped with more than 500 replaceable teeth.

Is there a volcano in Pennsylvania?
Q: Does Pennsylvania have any volcanoes? Today, Pennsylvania has no volcanoes.
Was Appalachian Mountains a volcano?
The Appalachians, a heavily forested mountain range stretching more than 1500 kilometers from Georgia to Maine, were not always so tranquil. In fact, about 460 million years ago during the Ordovician period, they were the site of one of the most violent volcanic events in Earth’s history.
Were there glaciers in Pennsylvania?
