GIS Day - Mapping our past with the help of RFID
Ages shown for divisions of geologic time are general representations. Ages in mega-annum mean millions of years before present. Box heights are related to how long time periods lasted; different scaling factors are used for the column on the front of the bookmark and for the column on the back, which represents a much longer time period. Map symbols are in parentheses. For more specific age information, see U.S. Geological Survey Fact Sheet 2018–3054 (https://doi.org/10.3133/fs20183054).
It’s Geographic Information Systems (GIS) Day! Since 1999 when it was first celebrated as the grand finale to Geography Week, GIS has been quickly put to use by many professions, industries and researchers. Today, GIS is becoming indispensable for paleontology - with the help of RFID.
The Age of Dinosaurs
According to the United States Geological Survey (USGS), the 'Age of Dinosaurs' (the Mesozoic Era) included three consecutive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods). Different dinosaur species lived during each of these three periods. For example, the Jurassic dinosaur Stegosaurus had already been extinct for approximately 80 million years before the appearance of the Cretaceous dinosaur Tyrannosaurus. In fact, the time separating Stegosaurus and Tyrannosaurus is greater than the time separating Tyrannosaurus and you.
At the beginning of dinosaur history (the Triassic Period), there was one supercontinent on Earth called Pangea. Many dinosaur types were spread across it. However, as Pangea broke apart, dinosaurs became scattered across the globe on separate continents, and new types of dinosaurs evolved separately in each geographic area (1).
When were fossils recognized as ancient dinosaur remains?
Fossils have probably been found throughout human history, despite not being recognized for what they are. Discoveries of their bones were often attributed to giant versions of known animals, or even giant people. Perhaps dinosaur bones inspired the stories of griffins, giants, and dragons.
Fossils of dinosaurs, described by a Chinese historian in the 4th century BCE, were labeled as dragon bones, while "dragon bones" were prescribed for ailments from madness to diarrhea. There’s no evidence as to the effectiveness of this treatment, however.
In 1822, Mary Ann Mantell was accompanying her husband, obstetrician, and paleontologist Gideon Mantell, on a visit to a patient in Sussex, England, when she noticed something at the side of the road. Looking closer, she found large teeth embedded into the rock.
Her husband Gideon realized that the fossil belonged to a creature unknown to science. He continued to study it and later named it Iguanadon after its iguana-like teeth. Later, paleontologist Richard Owen examined a number of fossil sets and concluded that Iguanodon, Megalosaurus, and Hylaeosaurus fossils were from "a distinct tribe or sub-order of Saurian Reptiles" which he termed, "dinosauria".

Earth Science
Today, an entire field of science is dedicated to the study of the earth, aptly named Earth Science. It includes four branches of study, including geology, meterology, oceanography and astronomy. Geologists specializing in the earth’s history are palentologists, and this group studies fossils to gather evidence to piece together what the ancient past might have been like.

It’s getting harder and harder to access places where fossils are plentiful and the Earth Sciences Foundation (ESF) was founded to help locate and protect fossils before they disappear. The foundation’s goal is to get people excited about and involved in earth sciences. Fields of study include everything from paleontology, to GIS to surveying.
One of the biggest issues facing scientists is keeping track of fossils, both in the ground and after they have been shipped to museums or universities for study. Recent headlines attest to the difficulty museums face in keeping track of all of their artifacts. Fortunately, there is an elegant solution to this pervasive (and costly) problem.
Each fossil was identified with a unique RFID tag that connected it to its record in ArcGIS. Data about the fossil was added throughout the process - accessible to all stakeholders in real time.
Berntsen has been working with The Earth Sciences Foundation to leverage the power of RFID to use GIS to track and manage dinosaur bones. Our InfraMarker Connected RFID has the potential to revolutionize how these precious artifacts are tracked from the time they are excavated until they are put on display in museums or sent to universities across the world for study. A simple RFID tag connected to GIS will allow scientists to see all the data about any specific artifact, including where it was found, photographs, video, notes and any other information about it, simply by accessing GIS. The RFID tag will stay with each artifact throughout its academic journey, making both the information and the location accessible at any time.
Dig to Display: Transforming Dinosaur Bone Asset Management with InfraMarker RFID and GIS

A recently-published study describes how dinosaur bones at Standing Rock Sioux lands in South Dakota were tracked from dig to display. ESF staffers used ArcGIS, Survey123 and InfraMarker RFID to track 347 artifacts from excavation to storage to display.
The bone tracking and management process is simple. Each discovered fossil was ‘tagged’ in the field with a tiny HID RFID marker to establish a unique digital and physical ID. That ID, and contemporaneous information, was captured by a field tech using a tablet with data collection software connected to a GIS platform. RFID scans of the bone’s tag tracked the bone as it moved through various zones from field to storage to cleaning to display, adding data to its GIS record. Simultaneously, hundreds of miles from the dig site, the contractor’s GIS platform displayed a map of original and current bone location and status as it moved from field to institute. Throughout the process, all RFID interrogation data was collected in the cloud, providing near real-time visibility of bone status by auditors hundreds of miles from the dig site.
Saves time; near perfect accuracy

Study results found a reduction of field data collection time by 80 percent, nearly perfect tracking of bones through the cycle from field to museum, and enabled easy data sharing and auditing of field work by related organizations.
The study demonstrated the benefits of the RFID/GIS integration that are making a huge difference in many industries - from utility management to agriculture, forestry and manufacturing. Another recent study shows how RFID can help identify and verify underground utilities, streamlining utility management and enhancing safety.
RFID and GIS - Accuracy, versatility and power
RFID and GIS expanding the benefits of location intelligence to new applications and streamlining access to valuable assets - from buried utilities to museum artifacts. Sales of RFID and GIS are exponentially growing because of the tremendous advantages these technologies offer across industries. When RFID is integrated with GIS through InfraMarker, accurate asset management is enabled by connecting the physical asset to its digital files that can be quickly accessed on-site with a simple RFID scan (or even a NFC scan from a cell phone). RFID provides asset authentication at the site of any asset, streamlining field work and improving accuracy and automatically generating tracking information. Any organization that needs to track and manage assets across space and time will benefit from incorporating InfraMarker RFID with their GIS.
