A geologist conducting routine field surveys in a San Mateo County preserve stumbled onto a fossilized Pacific mastodon molar in "immaculate condition", a find paleontologists are calling the most complete specimen ever recovered from the region. Brigid Lynch discovered the tooth partially submerged in a wooded creek bed while working on a California red-legged frog habitat restoration project in a Midpeninsula Regional Open Space District preserve in the Santa Cruz Mountains. She initially thought it was an oddly shaped rock. It was not. Paleontologists later confirmed the fossil was an intact upper left third molar from an adult Pacific mastodon, ABC News reported . The tooth measures roughly 8.5 inches long, 7 inches deep, and 3…Open

A scientist working to save a threatened frog species stumbled across a fossilized Pacific mastodon molar in a San Mateo County creek bed, a find experts are calling the most complete specimen of its kind from the region. Brigid Lynch, a geomorphologist at the consulting firm Balance Hydrologics, was surveying a wooded creek inside a Midpeninsula Regional Open Space District preserve in the Santa Cruz Mountains earlier this year when she spotted the nine-inch tooth sitting in plain sight. She was there for a habitat restoration project aimed at protecting the California red-legged frog, a threatened species. Instead, she found the remains of an animal that vanished from North America between 10,000 and 12,000 years ago. Lynch told…Open
A magnitude 3.3 earthquake shook Yellowstone National Park on Thursday morning, its epicenter running along the Yellowstone River roughly 24.2 miles from Mammoth, squarely inside the footprint of one of the most closely monitored volcanic systems on Earth. The U.S. Geological Survey recorded the quake at approximately 1:20 p.m. UTC, 8:20 a.m. Eastern, at a […] The post Magnitude 3.3 earthquake strikes Yellowstone near the supervolcano that keeps geologists watching appeared first on American Almanac .
A magnitude 3.3 earthquake shook Yellowstone National Park on Thursday morning, its epicenter running along the Yellowstone River roughly 24.2 miles from Mammoth, squarely inside the footprint of one of the most closely monitored volcanic systems on Earth. The U.S. Geological Survey recorded the quake at approximately 1:20 p.m. UTC, 8:20 a.m. Eastern, at a depth of 6.5 kilometers, or about four miles beneath the surface. No injuries, structural damage, or park closures were reported. By itself, a 3.3-magnitude tremor is modest. Most people nearby would feel little more than a brief rumble. But location matters, and few locations carry the geological weight of Yellowstone. The park sits atop a supervolcano that has produced three…Open
Colossal Biosciences — the company that's attempting to bring back the woolly mammoth and the dodo — revealed Thursday that it's aiming to revive another species: the bluebuck. Why it matters: The bluebuck — a member of the antelope family once found in modern-day South Africa — was hunted to extinction more than two centuries ago. Zoom in: Colossal said the bluebuck — which got its name from its silvery bluish hue — is the sixth member of the company's "de-extinction portfolio." - The company already generated global buzz in 2025 when it showed off multiple dire wolves , which had been extinct for more than 12,500 years. Colossal CEO Ben Lamm tells Axios that the company has obtained bluebuck DNA, mapped it and compared it…
A Texas biotech company is trying to bring mammoths and other extinct creatures back to life. The science is as intriguing as the ethical questions are thorny.
