Radiocarbon dating evidence for mammoths on wrangel island

To the east of Wrangel, along the edge of a bank of clouds, lies a much smaller landmass: Gerald, or Herald, Island.

The paisley-shaped clouds flowing away from Gerald Island are swirling eddies caused by the island’s obstruction of air flow.

The validity of our data has been confirmed by the results of our measurements on two international control sample series (IAEA and TIRI) and by parallel measurements of Wrangel Island mammoth remains at other laboratories.

Part of the Russian Federation, Wrangel Island rests above the Arctic Circle between the Chukchi and East Siberian Seas, northeast of Siberia.

The ghostly white shapes northeast and immediately southwest of Wrangel Island are sea ice.

Over the course of the satellite record, Arctic sea ice has advanced and retreated past Wrangel Island many times.

When it was learned in 2005 that Triceratops and Hadrosaur femur bones in excellent condition were discovered by the Glendive (MT) Dinosaur & Fossil Museum, Hugh Miller asked and received permission to saw them in half and collect samples for C-14 testing of any bone collagen that might be extracted.

Indeed both bones contained collagen and conventional dates of 30,890 ± 380 radiocarbon years (RC) for the Triceratops and 23,170 ±170 RC years for the Hadrosaur were obtained using the Accelerated Mass Spectrometer (AMS).

Russian scholars, however, claim to have discovered evidence for a "mammoth refugium" during the Holocene up until ~2000 BC.

Abstract: The discovery of collagen in a Tyrannosaurus-rex dinosaur femur bone was recently reported in the journal Science.

Its geologic location was the Hell Creek Formation in the State of Montana, United States of America.

) is an island in the Arctic Ocean, between the Chukchi Sea and East Siberian Sea. The International Date Line is displaced eastwards at this latitude to avoid the island as well as the Chukchi Peninsula on the Russian mainland.

The closest land to Wrangel Island is tiny and rocky Herald Island located 60 km (37 mi) to the east.
