Living earth iowa colony5/16/2023 ![]() This is an excellent example of digital fossil preparation via CT, which takes a fraction of the time that physical preparation takes and can be done without risk of damage to the specimen. The first image is a rendering of the specimen with matrix in left lateral view, and the second image has the matrix digitally removed. Figure 7.2 – CT images of Peltosaurus granulosus (AMNH FR 8138), a lizard that lived in the Oligocene (White River Fm., Wyoming) and was closely related to today’s Texas alligator lizard. CT is much faster at digitally removing the rock matrix (Figure 7.2). This can take from a few to tens of thousands of hours. For example, if you have seen trilobite specimens, these are often prepared by micro air blasting with talc to remove the host limestone. Using CT images also helps with fossil preparation as paleontologists often spend hours carefully removing rock matrix from a fossil. Image credit: Houston Museum of Natural Science, CC BY-NC-SA.

Much like when your doctor needs to look at your organs in detail, paleontologists use computed tomography (CT) with multiple x-ray scans to look through a fossil. From this, they can better look at the fossil’s internal structure. Recently, paleontologists have embraced the virtual world and computer-aided visualization to look at the three-dimensional structures in fossils. So, you never know if you’ll be the one to discover an interesting fossil that changes the way we think about the Earth. When the two of them went out to the fossil location, Jack Horner discovered the first fossilized dinosaur eggs in the western hemisphere. He realized that these were fossilized baby dinosaurs. Take the rock shop owner who showed Jack Horner a coffee can filled with tiny fossil bones. While most paleontologists are paid professionals, there are a large number of citizen scientists who make important paleontological finds. Paleontology is important to geobiology and is an interdisciplinary bridge between these two fields. Paleontology involves science, art, and imagination it inspires curiosity about ancient life and how the modern world evolved. Some of these include determining the origins of life on Earth and possibly other planets, climate change, biodiversity, changes in evolution, massive and small extinctions, and understanding deep time. ![]() ![]() Now, fossils are used in a variety of ways. For several centuries, fossils were the only tool geoscientists had to date rocks. Since then, new discoveries are being found all the time these change the way we tell Earth’s stories. ![]() Early Greek philosophers, such as Xenophanes (570-480 BC) and Herodotus (484-425 BC), recognized fossils as marine organisms. Ever since the first fossil was found, paleontologists have studied them to help decipher Earth’s history. Life on Earth has been around for a very long time, at least 3.5 byrs, and organisms have continually evolved and become extinct during this time.
