Excavation, Cosma, Peru

Grand Sized Mystery in Peru: Archaeologists Stumped over Giant Ceramic Structures that resemble Dinosaur Eggs

Getting your Trinity Audio player ready...

A giant and well-rounded discovery has been unearthed in Cosma, Peru. They look like the remains of  giant dinosaur eggs, but archaeologists believe the newly found structures are either giant pots or ossuaries for housing human remains.  Excavation will continue at the site to bring more information and hopefully more artifacts to light. Until then, Ancient Origins asks our readers to put on their thinking caps and analyze the large artifact recently uncovered.

New discoveries are underway at the Karecoto site near the village of Cosma in the Nepeña Valley, Peru and Co-project Director of the Proyecto Arqueologico Distrito de Cáceres Ancash (PADCA), Kimberly Munro was excited to share them with Popular Archaeology Magazine.

While Munro refrains from drawing any conclusions regarding the newest artifacts to the press, she has stated on her Facebook page that at least one was found to contain human remains.

"We're still excavating," posted Munro on her Facebook page, "but lots of Formative material inside as well with the there is another infant located on the outside of the olla - directly to the north of baby #1!"

The site of Karecoto is a large ceremonial mound complex, which has been dated to the Early Horizon period (900-1 BC) in Peru. “From the density and styles of the ceramics, and the different archaeological components, I believe Cosma has been continuously occupied since at least the Early Horizon,” Munro told Popular Archaeology Magazine.

Munro began excavations at Karecoto in 2014 with the goal to excavate and map the site elements. PADCA asserts on their website that this site is useful in the understanding of the "regional socio-political climate of highland and coastal Ancash during the Early Horizon."

In 2014 excavations at Karecoto, a series of raised platform structures (ceremonial temple mounds) complete with underground tunnels and galleries were found.

Karecoto measures about 250 meters (820 feet) long and 70 meters (229 feet) wide. The top is truncated and Munro told  Popular Archaeology in 2014 that it includes "Walls and domestic structures surrounded by what appear to be prehistoric canals."

Here we have an open window for readers and archaeologist aficionados to provide their suggestions of what the recent discovery may be. Is it a giant pot? If so, what was it used for? If it is not an ancient pot, what was it, and how was it used?

As excavation continues, more information will undoubtedly be provided.

The only thing I can think of is that these vessels resemble large sized ancient Greek and Roman olive jars.

The fact that one contained human remains tells me that they were probably used as funerary urns.

Dinosaur eggs?  How about ceramic containers? Isn't that enough of a description.  Besides, how many 3 foot diameter dinosaur eggs do we have to compare them to? The Scientists are stumped?


What do you do when you do not have the tools necessary to retrieve DNA?
