In May 2019, a construction crew working outside Denver, Colorado uncovered what appeared to be the fossilized remains of a dinosaur. As The Denver Post reports, paleontologists have traced the bones back to triceratops—the three-horned dinosaur that walked the Earth more than 65 million years ago.

The construction workers were digging up land in Highlands Ranch near the Wind Crest retirement center when they struck upon the fossils. The partial skeleton they found includes a limb bone and several ribs.

After studying the remains, paleontologists from the Denver Museum of Nature & Science confirmed that they once belonged to an adult triceratops. The rock layer containing the fossil was dated 65 million to 68 million years old. Triceratops went extinct 65 million years ago at the end of the Cretaceous period—they were among the last dinosaurs alive leading up to the mass extinction event that killed them.

After stumbling upon the prehistoric specimen, the construction team and Wind Crest have agreed to allow the museum to fully excavate the site in search of more bones. Meanwhile, the uncovered fossils have been wrapped in burlap and plaster and transported to the Denver museum to be examined further.

The exciting find isn't a first for Colorado. Triceratops accounts for most of the fossils found in the state. In 2017, a different construction crew working near Denver discovered a skeleton of the dinosaur that included its skull.

Archaeologists Discover the Jousting Yard Where Henry VIII Had His Historic Accident

Henry VIII may have never earned his reputation as an ill-mannered tyrant if it weren't for injuries he sustained at age 44. Now, as Live Science reports, archaeologists have uncovered the infamous jousting yard where that history-changing accident took place.

Prior to the beheading of Anne Boleyn—his second of six wives—King Henry VIII was regarded as a kind, gregarious leader by those who knew him. The point where descriptions of him changed their tone coincided with a fall he took on January 24, 1536.

While jousting at Greenwich Palace, Henry was tossed from his armored horse and further injured when his steed fell on top of him. The incident caused him to lose consciousness for two hours and nearly cost him his life.

Though it was never diagnosed, some experts believe Henry VIII sustained a brain injury that day that altered his personality. From that point on, he was characterized as irritable and cruel. He was in constant pain from migraines and an ulcerated leg, which could also explain the mood shift. The (sometimes violent) dissolution of most of his marriages occurred post-accident.

Ruins of the jousting yard, or tiltyard, where that fateful incident took place are located 5.5 feet beneath the Maritime Greenwich World Heritage Site, the former site of Greenwich Palace. After falling into disrepair, the palace was demolished by Charles II, and the exact location of the tiltyard was forgotten. A team of archaeologists led by Simon Withers of the University of Greenwich used ground-penetrating radar (GPR) to locate the remnants buried beneath the ground earlier this year.

The giveaways were the footprints of two octagonal towers. The archaeologists say these were likely the foundations of the bleacher-like viewing stands where spectators watched jousting matches. That would place the historic tiltyard about 330 feet east of where it was originally thought to be situated.

The radar scans provided a peek at what lies beneath the Maritime Greenwich World Heritage Site, but to learn more, the archaeologists will need to get their hands dirty. Their next step will be digging up the site to get a better look at the ruins.
