Dinosaur bone found under CO museum parking lot. See 67.5-million-year-old fossil
It all started with a 'geothermal feasibility project in the spring of 2024,' the Denver Museum of Nature and Science said in a July 9 News release.
The team had goals of drilling hundreds of feet below the surface with hopes to use 'the Earth's internal energy to heat and cool the museum,' researchers said.
But, what the museum didn't take into account during the project was it being led by scientists, making 'the urge to survey and study what's down there' 'irresistible,' researchers said.
The team began drilling over 763 feet below the museum's parking lot when they came across a 'major dinosaur discovery,' the museum said on Facebook.
Researchers found an 'ancient bedrock from the Late Cretaceous Period,' which didn't shock scientists – until they learned it contained a 67.5-million-year-old partial dinosaur bone, officials said.
'It's basically like winning the lottery and getting struck by lightning on the same day,' James Hagadorn, curator of geology at the museum said in the release. 'No one could have predicted that this little square foot of land where we started drilling would actually contain a dinosaur bone beneath it!'
The rock contained partial vertebrae of a 'plant-eating dinosaur, similar to a Thescelosaurus or Edmontosaurus,' researchers said.
This marks the 'deepest and oldest dinosaur fossil ever found within' the city's limits, officials said.
Smaller dinosaurs, like that of the Thescelosaurus, were 'agile and alert' hiding from their Tyrannosaurus rex predator and when the animals died, their remains would get buried into sediment that turned to rock after being carried through bodies of water, researchers said.
'In my 35 years at the Museum, we've never had an opportunity quite like this — to study the deep geologic layers beneath our feet with such precision. That this fossil turned up here, in City Park, is nothing short of magical,' Earth sciences research associate Bob Raynolds said in the release.
For those who want to see the fossil, the museum has curated a display.

Life might have come from outer space, scientist say
The seeds of life on Earth might have come from outer space – and might be widespread throughout the rest of the universe, scientist say. Researchers have found complex organic molecules in a disc around a 'protostar' in a major breakthrough. Those molecules are seen as the precursors to the building blocks of life, which go on to become sugars and amino acids that are then combined into the complex flora and fauna that surrounds us. Researchers have found such complex organic molecules in other places before. But the new findings fill in a previously mysterious missing link – one that could suggest that life is more abundant than we realise. When cold protostar becomes a young star, surrounded by a disc of dust and gas, it is a violent process that includes intense radiation and the hurling out of gas. Researchers had been concerned that the extreme nature of that process could 'reset' the chemical compounds available around a star, meaning that they would have to be formed in the discs that at the same time are making planets. But the new findings suggest that complex molecules can stick around through that process, meaning they will be inherited by the discs that follow. The findings are reported in a new study, 'A deep search for Complex Organic Molecules toward the protoplanetary disk of V883 Ori', published in the The Astrophysical Journal Letters.

Hints of Life on Exoplanet Recede Even Further
In April, a team of scientists based at the University of Cambridge claimed that a planet orbiting a distant star bore a possible signature of life. The announcement kicked up a fierce debate among astronomers, with many skeptics arguing that the evidence was too ambiguous. Now a NASA-led team has made a new set of observations of the planet known as K2-18b, which lies 124 light-years from Earth. They have provided a clearer picture of the planet — confirming the presence of water, perhaps even as a liquid ocean. But the new observations have failed to confirm evidence for life. In the original study, the Cambridge team claimed that K2-18b appeared to have a gas in its atmosphere that on Earth is produced only by living things. The NASA study did not find strong evidence for that gas. What's more, the NASA team argues that even if the gas was on K2-18b, it might have formed through mere chemistry. What once seemed like a promising clue of life — a biosignature — might be a mirage. 'A key takeaway is that biosignatures are going to be hard, no matter what kind of planet we are talking about,' said Jacob Bean, an astronomer at Cornell University, who was not involved in the study. The NASA team, working with the leader of the Cambridge group, posted its new results online last week. The scientists have submitted the study to a scientific journal for publication.

Watch these Starlink satellites whiz by as a comet makes a cosmic cameo
Recent space station inhabitant Don Pettit has shared a remarkable video showing dozens of orbiting Starlink satellites streaking across the dawn sky, photobombed by comet C/2024 G3 (ATLAS). Captured from the International Space Station (ISS) during his stay there earlier this year, the footage, which also includes a part of the station at the bottom of the frame, clearly shows a number of SpaceX's Starlink internet satellites moving from left to right in low-Earth orbit, and what appears to be the comet traveling in the opposite direction, far from our planet. Dozens of orbiting Starlink satellites streak visibly at dawn, photobombed by comet C/2024. — Don Pettit (@astro_Pettit) July 24, 2025 The difference in direction is due to the relative motion of the satellites, which orbit Earth and reflect pre-dawn sunlight, and the comet, which is distant and moving along its own trajectory across the sky. Recommended Videos SpaceX began deploying its Starlink internet satellites in 2019 and currently has around 8,000 of them in orbit, making it the world's largest satellite constellation. The Elon Musk-led company is aiming to deploy another 4,000 satellites, though the final constellation could expand to as many as 42,000 satellites. The more Starlink satellites SpaceX deploys, the wider the broadband coverage and the more reliable the service becomes. Starlink currently serves broadband internet to around 120 countries and territories, with more than 6 million customers on its books. But there's also a cost to having such a large constellation. Astronomers, for example, have been complaining for years that the growing number of Starlink satellites is interfering with their observations of deep space. The issue concerns sunlight reflecting off the satellites' surfaces. SpaceX has attempted to reduce the brightness of the reflected light by coating the satellites in a dark material, and also by adding reflective film to redirect the sunlight away from Earth. But that's not the only problem. Starlink satellites also emit radio signals that can interfere with sensitive radio astronomy observations, making it harder for astronomers to study the universe at certain wavelengths. As for Comet C/2024, it won't be appearing in other ISS videos anytime soon. The comet made its closest pass to Earth on January 13, coming within 8.7 million miles (around 14 million km) of our planet. But it's not expected to return for hundreds of thousands of years, so this particular flyby was a very rare approach. Interested to see more of Don Pettit's work?
