Using Geographical Information Systems (GIS) to quantitatively and visually identify and classify ammonoids by use of sutural templates will benefit the paleontological world, as well as biostratigraphers, geologists, and avocational paleontologists. Researchers will be able to use GIS software to match suture patterns within a set boundary and identify unknown suture patterns. Differences in suture patterns can be readily quantified. This method is user-friendly and easily accessible to most researchers. Other applications of this method could help us better understand suture formation and many other aspects of ammonoid paleobiology.
