16. A 17th-Century African Burial Ground

In 1991, a construction project for a 34-story federal office tower began, and preliminary archaeological research excavation found intact human skeletal remains located 30 feet below the city’s street level. During survey work, they discovered a six-acre burial ground containing upwards of 15,000 intact skeletal remains of enslaved and free Africans who lived and worked in New York. It had burial dates ranging from the 1630s – 1795, making it the earliest and largest African burial ground rediscovered in the United States.

They turned the burial ground into a national monument with an interactive visitor center and outdoor memorial.

17. A 700-Year-Old Mummy

In 2011, a working crew found a well-preserved mummy in what they described as a “brown liquid” underneath a modern road in China, in the city of Taizhou, in the Jiangsu Province. The mummy, a five-foot woman, is believed to be a member of the Ming Dynasty and was dressed in silk finery with robes, slippers, and jewelry, with her hair and eyebrows still intact. The director of the Taizhou Museum, Wang Weiyin, estimated her preservation period to be about 700 years old, and she is currently on display at the museum.

18. Mammoth Bones in a Stadium Field

Weirdly enough, we have another mammoth-related story. During a football stadium expansion project, construction crews uncovered large bones believed to belong to a mammoth from 10,000 years ago. Fortunately for all involved, Oregon State University has an archaeologist faculty member in-house who was able to head the examination. He and his students planned to comb through the pile of soil and bones to establish relevance and historical value – something that is quite enviable in the field! The students will have hands-on experience with carbon-dating and identifying extinct animal bones. According to the professor, there is no indication of human involvement with the remains.

19. A Severed Head at a Building Site

A man’s severed head was found in a Bedfordshire quarry, in Cambridgeshire, on May 16, 2016. The victim was believed to be between the ages of 30 to 50 and might have accidentally been hit by a train, according to the police. Furthermore, the head was thought to have been undisturbed for over a decade – and possibly from the 1960s – before the construction at the bridge structure loosened it.

Anthropologists and forensic dentists worked with the police officers to identify the man, scouring DNA databases, and missing person report from the National Crime Agency.

20. Human Bones Found at Aurora Construction Site

On February 14, 2019, many people were thinking of Valentine’s Day. This construction crew had other things on their mind: the human remains they had just discovered at the housing development they were working. The bones were found during excavation the previous day. The Colorado State Archaeologist assumed responsibility for the remains and the location site, and Necrosearch, a field team that assists with international site investigations, was on-site to help with a series of non-invasive methods. The body is believed to a male, likely over a thousand-year-old Native American.

21. A 300-Year-Old Ship at a Construction Site

During excavation for a new hotel site project in Old Town Alexandria, they unearthed a partial hull of a ship. The boat is large and imposing, believed to be from the late 1770s. Oddly enough, they made another historic discovery just two months prior on the same one-block site! Workers had discovered a building foundation from 1755 from a warehouse that was believed to have been the city’s first public building.

Naval archaeologists carefully dismantled the ship in search of any identifying characteristics that would tell us where it sailed or what it carried. There is no documentation of the ship’s existence, which makes it all the more exciting for those working on it!

22. Pablo Escobar’s Home Demolition Unearths a Safe

Workers demolishing a waterfront mansion once owned by the infamous drug lord Pablo Escobar discovered a safe in one of the remaining walls. Though the safe’s contents are unknown, many have contemplated that it contains cocaine or cash. They took the safe to an undisclosed location, and they will probably never show it to the public. Oddly enough, or perhaps not so strangely, considering Mr. Escobar’s lifestyle, this is not the first safe to turn up at a property he owns. Just a week previously, one was discovered and mysteriously vanished, with no word on its whereabouts.

23. Tombstones, Grave Markers, and Caskets

Oakbrook Terrace sounds like a sleepy little neighborhood, so they probably were quite surprised when the construction site next door dredged up tombstones and caskets. Condos were being built on the construction site, right next to Chapel Hill Gardens Cemetery. One Oakbrook Terrace resident called journalists to report the issue, who did a bit more digging. As it turns out, they moved the cemetery, and the owners claimed that all bodies along with it. The headstones were explained to be duplicate grave markers left from when the bodies were laid to rest there initially. Thankfully, they did not discover any human remains on the property.

24. Otters Found Under a Driveway

Usually, replacing your driveway seems like a straightforward task. It is less direct if you find a den of otters when replacing your driveway. That’s precisely what happened in Titusville, Florida. When they found them, the adult otter – presumed to be the mother – ran off and didn’t return. The Florida Wildlife Hospital and Sanctuary took over the care of the three otter pups. They were around three weeks old at the time. Typically, if you notice otter pups in the wild, it is best to leave them alone; their mom is probably nearby and will return, but, in this case, she did not. The cost of raising each otter pup is around $2,300.

25. A 33-Foot-Long Anaconda

Construction takes planning. Surprises tend to be a bad thing in the field, and workers were not prepared for the shock of a 33-foot long anaconda slithering out from a Brazilian cave. This 881-pound snake was unfortunately killed in an explosion when workers were detonating inside the cave in preparation of work on the Belo Monte Dam. If you have a fear of snakes, this discovery probably makes you slither away from your desk in disgust.

26. Ancient Church Found under Site for Shopping Center

As construction workers dug through the earth with a bulldozer in Palestine Square in downtown Gaza, bystanders took pictures and videos of the archaeological findings laid out in front of them. The project, formerly going to be a shopping center, was now turned into excavations for more historical pieces of what was previously a church from the Byzantine period. Unfortunately, the historical ministry’s budget is extremely limited in Palestine, and this site would require millions of dollars to carry out proper excavation for extraction and analysis, so there is a valid concern that some of the information it carries will be lost.

27. 600 Kilos of Roman Coins

Construction workers laying pipes in Seville, Spain have unearthed 600 kilograms, or 1300 lbs, or Roman coins, stored in 19 amphoras. The coins are bronze and silver-coated and spread across the 19 amphoras, 10 of which were intact, and just one meter underground. The currency was believed to be newly minted and used to pay soldiers or civil servants. The amphoras were extremely heavy, and they could not transport them easily. The coins bear the images of emperors Constantine and Maximian, the likes of which the Seville Archaeological Museum had never seen before. Of course, the regional cultural department has halted construction work in the park while archaeologists investigate further.

28. An Old Grenade Found in a Boston Construction Site

Bomb threats are taken very seriously, as they should be. So when construction workers found a grenade at their worksite in May 2016, it’s safe to say they took it very seriously. The workers were excavating a dirt embankment to build a concrete retaining wall along Queen Anne Road when they found a rusty metal grenade with white lettering along the side. One worker called his boss, who promptly told him to call the police. No one touched the grenade, which is the safest thing to do when you’re staring a missile in the face.

Boston State Police was able to identify it as a rifle grenade and removed it for disposal out of town. They said it was probably a device for training purposes now.

29. A Toddler’s Casket – and Her Ghost

When Ericka Karner was having her home renovated, construction workers found a small coffin under the garage. There were no identifying marks, so they nicknamed the girl in the coffin “Miranda.” They believed burial took place around 120 years earlier. She was thought to be left behind when the Odd Fellows cemetery moved away. When Ericka wanted to help bury her, the city wouldn’t allow it because she didn’t have a death certificate, so an organization called Garden of Innocence, which provides burials for unidentified children, stepped in to help determine Miranda’s identity. After nearly a year, they were able to identify her as Edith Howard Cook, who died on October 13, 1876, as a result of a protein deficiency, which would be easily curable today.

Until Edith’s burial was adequate, Ericka and her husband, in addition to the construction workers, said they heard toddler footsteps on the second floor. Now, Edith and her coffin rest peacefully in Colma’s Green Lawn Cemetery.

30. Lots of Dinosaur Eggs

Civilians first discovered fossilized dinosaur eggs in Heyuan in a construction site and mistakenly thought they were stones. Eggs have been found at multiple construction sites, like the batch of 43 eggs, with 19 of them intact. The project was then halted to see how many more were in the opening and how many they could preserve. The city calls itself the Home of Dinosaurs and has over 17,000 fossilized dinosaur eggs. Other dinosaur-related discoveries in Heyuan include dinosaur bones, skeletons, and footprints.

31. Whale Fossils on a California Beach

Construction crews working on single-family homes in the Santa Cruz mountains have discovered whale remains believed to date back to four million years ago. The construction site, located in Scotts Valley, now has a small team of paleontologists working to completely free the whale, estimated to be around 25 feet in length. The scientists have covered the bones in plaster to hold them in place and protect them during excavation. Not only is it the first whale of its age, but it is also the first mostly intact whale, which is what makes it so unique, says paleontologist Scott Armstrong.

32. 200,000-Year-Old Woolly Mammoth Bones

These contractors were lucky not to have to deal with human bones – instead, they discovered dozens of fossils from the Ice Age. Cornerstone Communities, a San Diego area contracting company, was developing a 636 unit subdivision in Carlsbad, California when they stumbled upon these ice age fossils. They’ve discovered skulls and partial skeletons from a bison, a woolly mammoth, an antique horse, and an antique turtle. California law does require a paleontologist be on-site when large amounts of dirt are being moved in case they find a fossil, so they quickly addressed the process in this situation.

33. Stone Tools Found in Redmond, Washington

Before construction even began on this project, archaeologists were brought on for an archaeological survey to clear the way. It quickly became apparent that there was more than met the eye at this particular site. By the time they finished, they had found more than 4,000 tools created over 10,000 years ago. Some of the devices even revealed traces of the food the users were eating, like bison, deer, bear, sheep, and salmon! The project was initially set to restore the salmon habitat in Bear Creek, but they delayed it as they attempt to protect and preserve the remaining artifacts.

34. Bodies Below Greenwich Village

The City of New York knew it could encounter human remains, which is why the group worked with archaeologists from the beginning of its project to install a water main. As workers dug near Washington Square Park, they found two burial chambers housing crypts thought to be over 200 years old. From 1797 to 1825, the area served as a public burial ground, which easily explains the dozens of bones found remaining in the field to this day. City officials worked to revise their construction plan to avoid any impact to the burial vault, which likely included changing the course of the subterranean pipes.

35. Pre-1906 Earthquake Chinatown Artifacts Found in Subway Construction

The Central Subway project, a line that would ultimately link Chinatown and South of Market in San Francisco, led to the discovery of what turned out to be 19th-century industrial sewing machines. They believed these sewing machines were used in the basement of a Chinatown factory that likely burned down or collapsed in the 1906 earthquake and ensuing fire. Sonoma State University was one of several archaeological consultants hired to assist with the excavation and analysis.

36. A Blast from MIT’s Past

A sealed glass time capsule that bears the hand-written note “Please do not open until 2957 AD,” has been found on the MIT campus by workers building the new nano-building. It contains a letter to the people of the next millennium and historical artifacts from the year 1957 when they initially buried it. Its design reflects that of the Westinghouse Time Capsule, buried at the 1939 World Fair.

According to MIT, this is one of eight time capsules the university has buried to commemorate various events, like the 1939 time capsule buried to celebrate the installation of a new cyclotron. They meant to recover the capsule in 1989, but they forgot about it under the 36,000-pound reinforced concrete slab.

37. A Mass Burial Site

In August 2015, while digging on Route 61 in Schuykill County, construction crews discovered a decade-old mass human burial site believed to have belonged to victims of the Spanish Influenza. Approximately 1,600 locals died in one month from the virus, and it was not uncommon for people to be buried in large unmarked graves like this one, as grave diggers could not keep up with the demand for individual graves.

They conducted DNA tests on the remains and gave proper burials to the individuals in the graves.
