In fact, the Garden State has one of the longest geological histories of any state in the United States with rocks going back more than million years, according to Dana Ehret, assistant curator of Natural History at the New Jersey State Museum. A tool from The Dinosaur Database can let you search your address and show you what your home would have looked like millions of years ago. The interactive globe lets you go from epoch to epoch where you can see how Earth's and New Jersey's landmass has changed as far back as million years ago.

Below, we will use the tool to go back through time and look at prehistoric New Jersey, which is represented by the pink dot. Ediacarian Period About million years ago.

New Jersey, at this time, was underwater and sea life was evolving with the advent of complex multicellular organisms. Most of the underwater creatures were soft-bodied life-forms that did not fossilize well. The fossilized remains of colonies of ancient cyanobacteria blue-green algae were found in the 1. Cambrian Period About million years ago. New Jersey, while still underwater, was a warm, shallow sea. It was a quiet geological time for the Garden State but evidence of Olenus, an ancient extinct arthropod as well as vertical worm borrows were found in Cambrian formations of northwestern New Jersey.

Olenus, an ancient Cambrian extinct arthropod. Silurian Period About million years ago. After a mass extinction took place where nearly half of marine invertebrate species were wiped out, the first land plants began to emerge during this period. In New Jersey, the Silurian period was marked by uplifting and mountain building with streams flowing northwestward across northern New Jersey. Permian Period About million years ago. The Permian Period is marked by merging of all landmasses and the creation of the supercontinent Pangea.

North America was going through significant uplift forming the Appalachian Mountains. Not a lot of fossils in New Jersey have been found from the Permian period. This may be, not because there was no life, but more likely, it was time of great erosion in New Jersey which could wash away the sediments that could preserve the organism, said Ehret.

The official state fossil of New Jersey, Hadrosaurus remains a poorly understood dinosaur, albeit one that has lent its name to a vast family of late Cretaceous plant-eaters the hadrosaurs , or duck-billed dinosaurs. To date, only one incomplete skeleton of Hadrosaurus has ever been discovered--by the American paleontologist Joseph Leidy , near the town of Haddonfield--leading paleontologists to speculate that this dinosaur might better be classified as a species or specimen of another hadrosaur genus.

One of the smallest, and one of the most fascinating, fossils discovered in the Garden State is Icarosaurus --a small, gliding reptile, vaguely resembling a moth, that dates to the middle Triassic period.

The type specimen of Icarosaurus was discovered in a North Bergen quarry by a teenage enthusiast, and spent the next 40 years at the American Museum of Natural History in New York until it was purchased by a private collector who immediately donated it back to the museum for further study.

Given how many states its remains have been discovered in, the foot-long, ton Deinosuchus must have been a common sight along the lakes and rivers of late Cretaceous North America, where this prehistoric crocodile snacked on fish, sharks, marine reptiles, and pretty much anything that happened to cross its path.

Unbelievably, given its size, Deinosuchus wasn't even the biggest crocodile that ever lived--that honor belongs to the slightly earlier Sarcosuchus , also known as the SuperCroc. You may be familiar with the Coelacanth , the allegedly extinct fish that experienced a sudden resurrection when a living specimen was caught off the coast of South Africa in The fact is, though, that most genera of Coelacanths truly did go extinct tens of millions of years ago; a good example is Diplurus, hundreds of specimens of which have been found preserved in New Jersey sediments.

Coelacanths, by the way, were a type of lobe-finned fish closely related to the immediate ancestors of the first tetrapods. New Jersey's Jurassic and Cretaceous fossil beds have yielded the remains of a large variety of prehistoric fish , ranging from the ancient skate Myliobatis to the ratfish ancestor Ischyodus to three separate species of Enchodus better known as the Saber-Toothed Herring , not to mention the obscure genus of Coelacanth mentioned in the previous slide.

Many of these fish were preyed on by the sharks of southern New Jersey next slide , when the bottom half of the Garden State was submerged under water. One doesn't normally associate the interior of New Jersey with deadly prehistoric sharks--which is why it's surprising that this state has yielded so many of these fossilized killers, including specimens of Galeocerdo, Hybodus and Squalicorax. The last member of this group is the only Mesozoic shark known conclusively to have preyed on dinosaurs, since the remains of an unidentified hadrosaur possibly the Hadrosaurus described in slide 2 were discovered in one specimen's stomach.

Marine crocodiles, plesiosaurs, and gigantic mosasaurs prowled the near-shore waters, and the dinosaurs Hadrosaurus and Dryptosaurus inhabited the land not too far from the ancient beach.

When these dinosaurs died, sometimes their bones were washed out into rivers and carried to the boundary of the sea, where they became fossilized along with the remains of marine animals. Unfortunately some of the most significant fossil sites in New Jersey have been built over or are no longer being examined, but there is one place where anyone can go to find fossils.

It is called Big Brook and is well known for the abundance of shark teeth and other small fossils. Every one in a while, though, someone finds a bit of dinosaur bone.

My familiarity with dinosaurs probably started as what dinosaurs were found in new jersey - what dinosaurs were found in new jersey did, with library books and grade-school field trips, and then over time faded down into maybe catching some films in the J urassic Park franchise. Now in my forties, I decided that a drive to southern New Jersey what dinosaurs were found in new jersey - what dinosaurs were found in new jersey reinvigorate that sense of childlike wonder.

And so it was that I wound up in Haddonfield, a borough in Camden County about 20 minutes from Philadelphia. For Haddonfield was once the source of a significant 19th century discovery that helped shape the course of much of modern-day paleontology.

It was in Haddonfield that the first nearly complete skeleton of a dinosaur was discovered in North America. I learned the story when I contacted Butch Brees, whose now-grown son, Christopher, played a major part in the saga. InChristopher, then a teenager, was working to make Eagle Scout, and it was his badge project that sparked renewed interest in this key piece of New Jersey history.

The South Jersey property where fossils were first found in the 19th century was farmland owned by John Estaugh Hopkins. InHopkins invited his friend William Ссылка Foulke, a Philadelphia lawyer and an avid natural historian, to dinner at his home.

In the course of their visit, Hopkins told Foulke about some bones he had found in a marl pit on his land about 20 years earlier apparently, some were given to friends as souvenirs or used as doorstops. Foulke was also a member of the Academy of Natural Sciences of Philadelphia.

Intrigued by what he heard, he asked Hopkins to take him to the site where the bones had been excavated. Then he requested permission to return with a digging crew. After the bones were confirmed as is trenton nj a good place to live dinosaur bones, paleontologist and Academy member Joseph Leidy came out to the site. The bones were then taken to the Academy now the Academy of Natural Sciences of Drexel Universitywhere they remain today. Ten years later at the Academy, English sculptor Benjamin Waterhouse Hawkins reassembled the skeleton and cast missing parts out of plaster.

When the reassembled skeleton was displayed in Philadelphia incrowds flocked to see the first reconstructed dinosaur in a museum. They were able to lay out the bones and cast pieces in between to really say, this is what a dinosaur looked like and how big it was.

According to Ted Daeschler, curator of vertebrate zoology at the Academy of Natural Sciences, 19th-century South Jersey farmers saw the ancient sediment had value. So, farmers dug up these sandy clay layers. Upon meeting officials from the Academy, and getting their support, Christopher and his fellow Scouts went to work to create a park to commemorate the digging site.

The park is located at the end of Maple Street, a side road off Grove Street the actual site is about feet past the park. Ina ceremony at the park with local and state officials celebrated its completion. A decade later, the site would be declared a National Historic Landmark. Two memorial markers—one mounted on stone, the other standing on a pole—acknowledge both milestones.

Butch continues to look after the site, and he keeps track of visitors through a guestbook. Ina sculpture of Hadrosaurus foulkii by artist and sculptor John Giannotti was placed in downtown Haddonfield on Hadrosaurus Lane. It has become a fun photo op. What happened then was that Chris created the site and brought a lot of attention [back] to the dinosaur being found in Haddonfield. Crossword Newsletters. TECH Disinformation.
