Seafloor layers off Japan may preserve hidden earthquake traces: radiocarbon analysis detected events that visual inspection, X-rays and CT scans had missed.
Radiocarbon analysis uncovers possible traces of hidden earthquakes off Japan's coast
Researchers at the University of Tokyo have used a new type of radiocarbon analysis to study a sediment core taken from the Kumano Sea off the coast of Japan.

Radiocarbon dating of the seeds places them between 800 and 760 BC. Researchers analyzed preserved hair from the burial mound. And, the burial also showed evidence of horse and human sacrifice.

By then we’ll have to radiocarbon his ancient butt to get his actual age.

Human consumption of psychoactive cannabis dates back at least 2,800 years, which is 300 years earlier than the oldest documented cases. Radiocarbon dating on some of the more than 1,000 seeds deposited in a Siberian tomb helped establish the time of origin.

Coptic children’s footwear from Egypt, dating from the second half of the 3rd century to the early 4th century AD.

Discovered in a burial site in Antinoöpolis, Roman Egypt. Dated to approx. 250–410 AD (confirmed via radiocarbon dating).

All dates in RIB made by modern scholars are adjusted in year to adhere to the Gregorian calendar. In antiquity, yes—and you also date by consulship. Read the translation and you will see it gives you day and month and then the year is added based on radiocarbon dating, context, or consulship.

Check out Lucia Snyderman @aukwardlucia.bsky.social et al.’s new paper on Great Auk 🐧 extinction timing! They compiled radiocarbon and observational data to estimate extinction timing for Great Auk populations across the North Atlantic. Link to paper: doi.org/10.1098/rsbl...
When dates disagree: radiocarbon and sighting-based models reveal range-wide variability in great auk (Pinguinus impennis) extinction estimates
Abstract. Methods for inferring extinction are well established for events that either occurred on millennial time scales (e.g. the late Quaternary) or are

(It’s a book called The Jesus Conspiracy, which also claims that the Catholic Church pulled some strings to falsify the Shroud of Turin’s radiocarbon dating results in an effort to cover this all up, because it would disprove Jesus’ resurrection)

Excavations at Las Minillas in Badajoz found 735 grooved stone hammers and 17 radiocarbon dates, and 11 Nordic bronzes fit its copper.
Archaeologists discovered hundreds of stone hammers at a Spanish copper mine that likely traded its metal with Scandinavia

That’s the point: per the conspiracy theory, the Shroud was actually Jesus’, and examining it proves that he was alive in the tomb; so to cover up the fake resurrection, the Catholic Church had the Shroud’s radiocarbon dating manipulated to make it look like it’s from the Middle Ages

“….the archaeologists found more than 1,000 cannabis seeds. Radiocarbon analysis dated them back to the early eighth century B.C.E.

The real breakthrough, though, was in the human hair recovered from the burial sites, Caspari says. It contained cannabinol, a chemical produced from THC...”

Radiocarbon-based models estimate extinction later (post-2000 CE) across the species’ range, suggesting inherent uncertainties in radiocarbon dates and their calibration may constrain their applicability for detailing extinction processes on conservation-relevant timescales.

Texas during the Last Glacial Maximum was on average 5 C cooler than today, with summers 2 C cooler. The mean annual temp of Texas can be up to 20 C today (although some parts are colder), I think they'd be okay at 15 C.

Worth adding: radiocarbon dates published in 2014 put the Serpent Mound's construction near 1070 CE, in the Fort Ancient period, rather than the Adena era many older accounts assumed. The dating is still debated, since earlier charcoal samples gave older results.

The sky left a timestamp in the trees. A 2021 study used the AD 993 radiocarbon spike and tree rings to date Norse woodcutting at L’Anse aux Meadows to AD 1021. That's a year of activity, not a first-arrival date.
