If you visit New York City's famed Central Park, consider stopping by the Egyptian obelisk located behind the Metropolitan Museum of Art. The white limestone base the granite obelisk rests on contains a lot of visible fossils. The obelisk (known as Cleopatra's Needle) were created to celebrate the 30 year reign of pharaoh Thutmosis III (1479-1425 B.C).
Their original location was at the Temple of the Sun in Heliopolis, Egypt. They were constructed from pink granite at the quarries in Aswan. Roman Emperor Augustus had them moved to the temple Caesarium around 12 B.C.
The Khedive Ismail Pasha of Egypt exchanged this obelisk for economic aid from the City of New York, United States in 1881. Earlier, it's twin obelisk was transferred to London, England in 1878.
The Romans added an Egyptian limestone base and steps plus 4 bronze crabs to stabilize the obelisk on its new base. Only two of the crabs partially survived when the obelisk was being made ready for transfer to the United States. Once it arrived, Brooklyn Navy Yard workers forged four new 418 kg metal crabs in about 10 days. Molten lead was used to secure the crabs to the obelisk thus re-enforcing the broken corners. The claws are inscribed in English telling of who replaced them.
The remains of the two original Roman bronze crabs are on display at the
Metropolitan Museum of Art in the Temple of Dendur exhibit. It looks like they were mostly plundered for their metal or as souvenirs by long ago visitors. The claw has a Greek inscription on the outside stating Roman prefect Barbarus and architect Pontius erected the obelisk in the 18th year of an emperor (Augustus?). The original metal crabs were donated by Lt. Commander
Henry H. Gorringe who transferred the obelisk to New York in 1880-1881.
When I first encountered the base I was not sure what type of fossils it was covered with at first I thought they might be pelecypods or brachiopods. Now I am convinced they are foraminiferan
Nummulites fossils.
The fossils are somewhat worn, but the picture on the right with two orange arrows showing two
Nummulites with their tops or bottoms cross sectioned.
The base and steps appear to be composed of an Eocene limestone from Egypt. This type of limestone was used to construct ancient Egyptian structures so they contain these fossils as well. Learn more at
Wikipedia.
Most of the fossils I saw appeared to be
Nummulites stacked on top of one another but picture on the left looks like a gastropod or ammonite whorl.
The picture on the right has an orange arrow pointing to what appears to be a fossil with some sort of spines. It might be a spiny brachiopod or some sort of echinoid.
So if you get a chance to visit New York City's Central Park, allot some time and visit the oldest man-made object in the park.
