Can you imagine the world’s oceans filled with carnivorous reptiles? Dinosaurs are the most famous members of the age of the reptiles. However, many of the original reptilian fossil discoveries that initiated the idea of the age of reptiles were not dinosaurs. They were instead reptiles that lived in the sea.
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 →
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 →
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 →
"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."
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 →
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 →
Our perceptions of the age of an object are frequently based on our common experience but I have found that for many people those common experiences are of little help when it comes to examining objects for which a person has no experience at all. A couple of years ago this really hit me as... Continue Reading →
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 →
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 →
Anyone who has spent time in a desert has probably noticed many dark streaks or patches on the rocks. I expect that most people simply look at these dark streaks and think they are simply stains like a stain on a cement driveway or that line of rust color running down a wall from a...

Travel to most any desert region and you will observe black, brown or orange streaks or crusts on the surface of many rocks. These stains on the rock have been called desert or rock varnish. The origins have been scrutinized for many years and still are not fully understood. I will explore some of what... Continue Reading →
Just how fast are some rocks on Mars eroding? A few months ago I asked a Martian rock that question (see: My Interview with a Martian: A Story of Origins) and I was not given a very satisfying answer. Well, that rock can be excused for being a bit confused about time given how boring... Continue Reading →
Curiosity keeps chugging away across the floor of Gale Crater. A few weeks ago we talked to a rock (My Interview with a Martian: A Story of Origins) that it met as it is working its way to the base of Mt. Sharp. I had mentioned that the trip has been a tad boring compared... Continue Reading →
Inverted valleys formed from lava "rivers" and ancient stream beds are one of many unusual geological phenomena found in Utah. The rocks speak in Utah and they speak very clearly because they readily reveal so many clues about their origins since they are so visible to us. Some of the most powerful testimonies of...
