[1]:p.8 Instead, the initial papers on Tanis conclude that much faster earthquake waves, the primary waves travelling through rock at about 5km/s (11,000mph),[1]:p.8 probably reached Hell Creek within six minutes, and quickly caused massive water surges known as seiches in the shallow waters close to Tanis. Jim Garvin, the chief scientist at NASA Goddard, said it would be fascinating to compare the Tanis fragments with samples collected by NASAs OSIRIS-REX mission, a spacecraft currently en route to Earth after a visit to Bennu, a similar but smaller asteroid.

When an asteroid or possibly a comet hit Earth some 66 million years ago, it struck the planet off the Yucatn Peninsula in present-day Mexico. The evidence is stacking up, and at Tanis, a top-secret location in North Dakota, scientists are uncovering the first direct evidence, from the exact day, that the dinosaurs were wiped out 66 million years ago. Aquatic organisms are mixed in with the land-based creatures. Science usually demands the initial presentation of new discoveries is made in the pages of a scholarly journal. BBC Studios But Tanis was more than 2,800km (or 1,800 miles) away. Tanis is the only known site in the Hell Creek Formation where such conditions were met, [so] the deposit attests to the exceptional nature of the [Event]. One Of Richest Fossil Resources In The World Crossed By Keystone - SDPB The limb, complete with skin, is just one of a series of remarkable finds emerging from the Tanis fossil site in the US State of North Dakota. The second was a layer of melt spherules: tiny glass balls that cooled in flight from molten rock. When the asteroid impact theory was first proposed in 1980, there was no crater. The North Dakota fossil site is a chaotic jumble. Thats the claim of palaeontologist Robert DePalma and colleagues, whose work was captured by the BBC in its recent landmark documentary Dinosaurs: The Final Day with David Attenborough. First, theres an exceptionally preserved leg of the herbivorous dinosaur Thescelosaurus, which shows not only the bones, but also skin and other soft tissues.

NOVA Dinosaur Apocalypse premieres Wed., May 11 at 9 p.m. Eastern time on PBS. Taken together, this suggests the meteorite struck in May or June, being the cusp of spring and summer in the northern hemisphere. There are no signs that the dinosaur was killed by a predator or by disease. The Mesozoic terminated in boreal spring | Nature Now, paleontologists working in North Dakota believe that theyve found a number of unlucky creatures who died on that fateful day. With modern X-ray technology it's possible to determine the chemistry and properties of the egg shell. The event included waves with at least 10 meters run-up height (the vertical distance a wave travels after it reaches land). By comparing living sturgeon to sturgeon fossils from Tanis, they found that in a fin spine, regular layering at a scale of millimeters shows the fish died when it was seven years old. 1201 Bogota. The North Dakota Geological Survey runs public dinosaur digs in four locations across the state: Bismarck, Dickinson, Medora and Pembina Gorge. Unfortunately, many interesting aspects of this study appear only in the New Yorker article and not in the scientific paper, says Kirk Johnson, director of the Smithsonians National Museum of Natural History. Bottom line: Scientists have pinpointed the exact month of dinosaur extinction to be June, by looking at sediment layers in North Dakota, and fossil water lilies.

It seems like the geochemical data are scant and in some cases being stretched a bit to make interpretations, Montanari says, although this is not a new thing for paleontology. These data points can be used to measure when and how quickly the Tanis site formed, critical details when attempting to determine what the site actually records.
