French botanist Adolphe-Théodore Brongniart is known as the Father of Paleobotany. Active in many branches of botany, Brongniart is most-remembered for his pioneering work on the relationship between extinct and living plants. In 1822, he published a paper on the classification and distribution of fossil plants, which he subsequently followed-up with his masterpiece Histoire des vegetaux fossiles (“History of fossil plants”) in 1828.

If you’ve seen Jurassic World (or even just the trailers), then you’re familiar with Mosasaurus.

Most people today are at least somewhat familiar with the order of extinct marine reptiles known as Plesiosauria, thanks to the legend of the Loch Ness monster, which is often described as resembling a plesiosaur. Indeed, some argue that Nessie may in fact be a surviving member of this order. Scientists, however, reject this suggestion, if for no other reason that the Loch Ness lake formed a mere 10,000 years ago, while the fossil record indicates that plesiosaurs went extinct over 66 million years ago. And yet, even if plesiosaurs can’t account for the Loch Ness legend, the story of their discovery is still captivating. Plesiosaurs are among the first extinct fossil reptiles to be recognized as such.

We’re so excited that our #FossilStories Citizen Science Challenge was successfully completed on October 12, with 252 pages from 9 field books fully transcribed and reviewed in just 3.5 days! Be sure to tune into the behind-the-scenes tour of Smithsonian fossil collections with Dr. Nicholas Pyenson, Curator of Fossil Marine Mammals at the Smithsonian’s National Museum of Natural History, via the BHL Periscope on October 26 as a reward for the successful completion of the challenge.

The Smithsonian National Museum of Natural History’s FossiLab is a busy place, responsible for preparing newly-collected fossils for Smithsonian’s scientists and maintaining the fossils in the Smithsonian’s collection. Visitors to the museum can actually watch staff and volunteers at work in the FossiLab, which is located within the Last American Dinosaurs Exhibition. One of the projects in the FossiLab is the conservation and rehousing of specimens from the Museum’s fossil marine mammal collection. The specimens range from individual teeth to skulls, jaws and more-or-less complete skeletons comprised of both intact and fragmentary bones.

At the end of the eighteenth century, Jean Léopold Nicolas Frédéric Cuvier, also known as Georges Cuvier and widely remembered as the Father of Paleontology, helped establish extinction as a fact and laid the foundation for vertebrate paleontology. Born in Montbéliard, France, in 1769, Cuvier formed an interest in natural history at a young age, and by the time he was 26 (in 1795), he became the assistant of Jean-Claude Mertrud, the chair of comparative anatomy at the Jardin des Plantes.

By the seventeenth century, it was still widely believed that species could not become extinct, and there were still many hypotheses about the origin of fossils. One widely-held belief, extending back to Aristotle’s time, was that fossils were formed by the Earth itself, and that some “extraordinary Plastick virtue” could create stones that resembled, but were not, living organisms. But also during the seventeenth century, some critical advances in the world of science were having an impact on fossil research. Robert Hooke was born at Freshwater, on the Isle of Wight, in 1635. Though of humble origins, he eventually studied at Oxford and impressed many of England’s leading scientists with his ability to design experiments and build equipment.
