Schweitzer noted in a 1997 article [3]: We also thought hemoglobin could be in the tissue because at its core are structures that have a reputation for durability.In the mid-1990’s she did a couple of chemical tests with the dinosaur bones.Spectroscopic tests of light wavelengths emitted or absorbed indicated that somewhere in the fossil bones were compounds that were consistent with heme.The southern margin of the Zhucheng Basin may be a secondary source area.This research provides an important basis for judging the deposition time and the sediment source of fossil layers in the Wangshi Group, as well as reconstructing the palaeogeography of the Wangshi Group in the Jiaolai Basin.A relatively new area of controversy is the discovery of soft tissues in dinosaur fossils.The state of these discoveries changes every few years, so some of the standard science web sites have not kept up.A 2009 Institute for Creation Research article by B.Thomas [1] leads off: Since many think of a fossil as having had the original bone material replaced by minerals, the presence of actual bone–let alone pliable blood vessels, red blood cells, and proteins inside the bone–is quite extraordinary. Given the fact that organic materials like blood vessels and blood cells rot, and the rates at which certain proteins decay, how could these soft tissues have been preserved for ten thousand, let alone 65 million or more, years?If these objects were red blood cells, how could organic matter be preserved for more than 65 million years, when the last of the dinosaurs died out?Schweitzer has spent the last two decades trying to answer these questions.
