70850 Schur           Discovered 1999 Nov. 4 by the Catalina Sky Survey.
Chris (b. 1958) and Dawn Schur (b. 1960) are amateur astronomers and amateur paleontologists living in Payson, Arizona. Their astrophotography at their home observatory is of the highest quality and the analysis and cataloging of fossils posted on their extensive website, is quite professional.
