What is Tanis (fossil site)?
The '''Tanis fossil site''' has a unique place in Earth history. It preserves a record of what happened when the [[asteroid]] struck Earth 65 million years ago. The site is in [[North Dakota]] in part of the [[Hell Creek Formation]], famous rocks where [[dinosaur]] fossils are found. Tanis seems to record the events immediately after the impact of the giant [[Chicxulub]] [[asteroid]] in extreme detail. The fossil fish from this site are covered with [[debris]] from the impact at [[Chicxulub]]. The site was excavated by Robert DePalma over several years. He started in 2012, working in secret.<ref name=DeP>DePalma, Robert A. ''et al'' 2019. A seismically induced onshore surge deposit at the KPg boundary, North Dakota. Proceedings of the [[National Academy of Sciences]]. '''116''' (17): 8190–8199 [https://pubmed.ncbi.nlm.nih.gov/30936306/].</ref> Key findings were presented in two conference papers in October 2017. The full paper introducing Tanis was widely covered in the media on 29 March 2019, ahead of its publication three days later. The co-authors included [[Walter Alvarez]] and [[Jan Smit (paleontologist)|Jan Smit]], both experts on the K-Pg impact and extinction. == References == {{Reflist}} [[Category:Lagerstätten]]
