I have one plant in my office that I have managed to keep alive for 5 years but mostly I keep organisms in my office that can't be killed because they are already dead. I'm a bit more extreme in my lab where I keep thousands of samples of DNA in freezers. In my office I... Continue Reading →
Mary Anning: Plesiosaurs, Pterosaurs and The Age Of Reptiles
What do you think of when someone mentions the Jurassic or Cretaceous ages? Most likely you will immediately think of dinosaurs and other large reptiles such as pterosaurs. Maybe you think of the movie Jurassic Park, filled with dinosaurs and lush vegetation. This time has become known as the Age of the Reptiles and aptly so since... Continue Reading →
NH Notes: Biggest Dinosaur Ever Found But Is It The Largest Animal?
What is the largest animal to have ever lived on the Earth? Most people will answer “dinosaurs” or “sauropods” in particular. While some titanosaurs may have been the heaviest land animals they were not the largest animals to have lived on Earth. That distinction goes to an animal that is very much alive today: the...

Imagine you live in northern England and you are out exploring and come upon a hidden cave entrance. Upon climbing down into the cave you discover hundreds of bones belonging to large mammals. At first you think the bones represent local animals since there are some deer, rabbits, weasels and wolves but soon it becomes clear... Continue Reading →
NH Notes: An Ode to Coprology
"Approach, approach, ingenuous youth, and learn the fundamental truth: The Noble science of Geology Is founded firmly in Coprology. For ever be the Saurians blest, Who left us this diluvian test. I claim a grand coronam lauri, For these, Thesauri of the Sauri."
William Buckland: Minister and Geologist Grappling with Fossil Feces, Deep Time and the Age of Reptiles
The Reverend William Buckland (1784-1856) was one of the last in a line of influential natural theologians following in the footsteps of John Ray (late 1600s) and William Paley (late 1700s). I recently gave a seminar in which I explored a number of significant turning points (figure below) in the history of discovery of deep time and the awareness... Continue Reading →
Historical Science and the Case of T. rex’s Puny Arms and Dinosaur Diets
Everyone has encountered a T. rex in books, movies or museums. Besides its size and menacing jaws one of the most striking features of a T. rex is its diminutive arms. So why were the arms of T. rex so short? There have been many hypotheses including: 1) they had no use and... Continue Reading →
Geological Context V: Human Fossil Footprints Found Below Ice Age Deposits
A story is breaking today of a significant fossil find made almost a year ago but kept under wraps until the data could be properly evaluated. What has now been revealed is that over 100 footprints were found in newly uncovered rocks along a shoreline of England. Study of these footprints has led to... Continue Reading →
Fishing for Fossils in the North Sea: The Lost World of Doggerland
Imagine trawling for fish and when you pull up your nets you find a massive bone or a huge tooth along with your catch. For over 100 years fishermen in the North Sea between Britain and Denmark have found such items in their nets but it wasn’t until the 1980s that their value, monetarily and... Continue Reading →
Juvenile Dinosaurs Found Huddling in a Nest: A Local or Global Catastrophe?
We live in a new golden age of fossil discoveries. It seems that every week a new and dramatic fossil find is revealed. This fossil renaissance can be attributed to the opening up of new fossil sources, particularly China and Mongolia but also South America and to improved technology for retrieving and analyzing fossil remains....

NH Photography: Badlands National Park, South Dakota
A visit to Badlands National Park in South Dakota feels a bit like going to see a miniature replica of the Taj Mahal instead of seeing the real thing after you have hung out for a week in Moab UT and traveled around southeastern Utah. But that isn't to say that it isn't worth seeing. On... Continue Reading →
A Tale of Taphonomy: Clam Shrimp Fossils and the Age of the Earth
One of the great privileges of my job is that I get to participate on committees of graduate students. This allows me to get up close and personal with data from sub-disciplines of biology that often extend far from those of my particular expertise. You know by now that I carry a particular fondness for... Continue Reading →
NH Notes: A Fossil Scallop from Calvert Cliffs, MD
A colleague has a fossil scallop in his office that he collected while teaching a field course on Chesapeake Bay biology. He pulled this scallop from the cliff wall at Calvert Cliffs near Calvert, Maryland. It is particularly impressive not only for its size (more than 5 inches in diameter) but also for its condition.... Continue Reading →
Geological Context IV: The Pit of Bones – An Ancient Death Chamber
Down a 43 foot vertical shaft, another 40 foot slope, and buried under thousands of cave bear, lion and lynx bones, lies the partially fossilized bones of at least 30 individual humans. Welcome to a chamber of horrors otherwise known as Sima de los Huesos (the pit of bones). This pit is but a small... Continue Reading →
Rapid Burial Allows Preservation of a Hadrosaur Fleshy Head Comb
A mummified fossil of common species of hadrosaur was found recently in South Dakota that showed that this particular hadrosaur had a rooster-like fleshy comb on its head. Many hadrosaurs have exotic extensions of their cranial bones but this evidence that even the “boring” hadrosaurs had fleshy projections suggests that the hadrosaurs were an even... Continue Reading →
