Billions of footprints are preserved in the rock record. While bones get all the attention, fossil footprints, a type of ichnofossils outnumber bones. How can we make sense of this observation? Surely, preserving a bone must be far more likely than preserving a footprint? I have written about how paleontologists use information from footprints and bones... Continue Reading →
Young Mars Creationism: What Happened to the Water on Mars?
Mars once had a thicker atmosphere and liquid water on its surface. Nearly every month data from satellites and multiple ground-based systems provide new evidence confirming what was once speculation about the watery past of Mars. But how much water and how long ago did this water exist? A large amount of water still exists on Mars... Continue Reading →
The Mosquito That Produced More Than A Little Buzz
Paleontologists can get excited about fossils even if they are not dinosaurs, mammoths and hominids though this story has a Jurassic Park dino connection which helps. In this case several tiny fossil mosquitos had scientists abuzz in 2013. Fossils of mosquitoes are known from amber (fossilized tree sap) but are extremely rare in sedimentary rock...

Amazonian Forest Islands: Accidental Products of Ancient Human Occupation
The Amazon basin isn’t all a lush tropical forest. In large portions of western Amazonian wet seasonally flooded grasslands--not trees--are the norm. The upper branches of the Amazon River wind themselves across massive flood plains like snakes writhing across a sandy surface. One feature of these nearly featureless flat plains that has long puzzled... Continue Reading →
The Best Critique of Flood Geology Written by a Flood Geologist
Young-earth creationists have been wrangling for decades over how to identify where the Flood/post-Flood boundary is to be found. I described the most popular hypotheses put forward by YECs in a recent post, Where is Noah's Flood in the Geological Column? I have also recorded a YouTube video based on this article. https://www.youtube.com/embed/7gEwLe6c3Wg There is... Continue Reading →
Where is Noah’s Flood in the Geological Column?
Young-earth creationists have a geological column problem that 50 years of research has yet to solve: where is the boundary between Flood deposits and post-Flood deposits?
Multituberculates and the YEC Flood/post-Flood Boundary Problem
Yes, multituberculates have something to say about the ongoing division among YECs about where to locate the Flood/post-Flood boundary in the geological column. Is that boundary to be found in the Quaternary, at the Cretaceous/Paleogene boundary or way down in the Pennsylvanian Period? These are the three primary models that YECs have proposed. The problem... Continue Reading →
The False Hope of a Mature Creation
Strike up a conversation about the age of the earth with nearly any group of evangelicals and you are sure to get a lively discussion. There may be a young earth defender who will pull out some Ken Ham top-10 proofs of a young creation, some will claim to be agnostic on the topic while... 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 graduate student committees. Many times this allows me to get up close and personal with data sub-disciplines extend far from those of my particular expertise. You know that I have a fondness for fossils and the stories they tell. So... Continue Reading →
The Toba Super Eruption, Polar Ice Cores, and Climate Change
I recently discussed how the catastrophic Toba super-eruption in Indonesia is a serious challenge to the young-earth model of earth's history (The Toba Super Eruption: A Global Catastrophe that Creationists Ignore). Briefly, I explained that the Toba volcano caldera produced the largest eruption in the past 100,000 years releasing an estimated 2800 cubic kilometers of... Continue Reading →
The Toba Super-Eruption: A Global Catastrophe that Young-Earth Creationists Ignore
Sudden catastrophic events are not unknown in earth’s history. Large craters are evidence of past cosmic impacts and widespread layers of volcanic ash are a testimony to massive volcanic eruptions. But when did these catastrophes occur and could they have influenced human history? Standard geological models place the largest catastrophic events far in the past. ... Continue Reading →
A Walk on the Beach Preserved in Stone–How Fossilized Turtle Tracks Refute Young-Earth Fossil Dogma
Baby sea turtles emerge from their sandy nest and quickly make their way down the beach and into the sea. As they do so they leave tiny footprints in the sand, but the tracks are short-lived. Blown away or destroyed by the next large wave, they are lost forever. Imagine the footprints you leave during... Continue Reading →
Ignoring the Plank: A Young-Earth Apologist Inadvertently Writes a Brilliant Critique of Young-Earth Creationism
How should a movement dedicated to science denial warn its adherents against the evils of science denial? Young-earth creationism finds itself faced with just this problem as some of its followers slip toward the flat-earth fringe. Answers in Genesis, the leading young-earth apologetics ministry, has responded by critiquing the flat-earth movement in a series of... Continue Reading →
The Appearance of Age and the Origin of the Hawaiian Islands
What is the origin of the Hawaiian Islands? The exploration of that question consumed my attention for several years. At that time—way back in the 1990s—I was a post-doctoral researcher at Southern Illinois University sequencing chloroplast genes from holoparasitic plants. At the same time I discovered list-serve discussion groups, I was given creation science literature... Continue Reading →
Stranger Things–Creationist’ Views of Speciation and Natural Selection in the 1980s
Today, young-earth creationists are actively promoting a new model of the origin of the diversity of life on Earth. This speculative view borrows a number of elements found in any typical evolutionary biology textbook. For example, modern YECs claim that most and possibly all species alive today—except humans—are related to numerous other, though not all,... Continue Reading →
