Obtaining fingerprints for identification is a long established law enforcement practice. When the practice started, is was most common to use printers ink applied to the fingers which were then pressed onto paper cards. Later specialized inks were employed to improve the quality of the prints obtained. While ink is still used today, many agencies are now using computer "live-scan" methods to record reference prints.
One of the challenges in obtaining reference prints has always been how to obtain them from the deceased. Ink has often been used with success, but it can be difficult, especially with rigor stiffened or mummified fingers. Live-scan is not a practical option, at least not until someone develops a portable scanner. Last Updated on Monday, 26 October 2009 12:39 Read more... PALYNOLOGY: The branch of science concerned with the study of pollen, spores , and similar palynomorphs, living and fossil. Term suggested by Hyde & Williams (1944). Etymol. Greek "to strew or sprinkle", suggestive of "fine meal" cognate with Latin pollen, "fine flour, dust."

Lower Hutt, New Zealand IntroductionThe term "forensic palynology" is rarely used in the United States. Forensics pertains to evidence used in courts of law. Palynology is the term first used by Hyde and Williams (1944) for the collective study of pollen grains and spores. Years later, the discipline of palynology was expanded to include the study of a number of other acid-resistant microorganisms as well.
Today, the science of forensic palynology traditionally focuses on legal evidence derived from the study of pollen and spores, both fossil and modern. In its broader application, the field of forensic palynology also includes legal information derived from the analyses of other palynomorphs such as dinoflagellates, acritarchs, and chitinozoans. However, in most sampling situations forensic palynologists rarely encounter these other types of acid-resistant palynomorphs because most are marine and many are restricted only to fossil deposits.

Today, the country of New Zealand leads the world in the use of forensic palynology, and the acceptance of this type of evidence in courts of law. To illustrate how important, and diverse forensic palynology has become, we have briefly examined a number of actual circumstances where these types of techniques have proven useful. In most of these cases the palynomorph data were an important factor in either solving the case, or they were used to identify and link a suspect to the scene of a crime. We also discuss some of the strengths, and weaknesses, of using forensic pollen data, and why we feel this technique is still neither widely accepted nor used in most of the countries of the world.
