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 →
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 →
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 →
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 →
During the last Ice Age when the oceans were up to 300 feet lower than they are today, an extensive cave system on the Yucatan Peninsula of Mexico was exposed, above sea level, allowing it to potentially be occupied by animals and humans. When the massive ice sheets melted from the Earth’s surface causing the... Continue Reading →
The evidence continues to accumulate: Mars used to be wet. It used to have a much more active hydrological cycle. The Mars Couriosity Rover has been revealing the complex geology of Mars including the deposition of sedimentary rocks (Curious Geology: Stunning Images Reveal a Complex Mars) but we have been able to study the watery...

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 →
One of the largest volcanic eruptions in earth’s history, the Toba super eruption has been a special interest to anthropologists and climatologists because of its potential impacts on past human populations. I have explored the implications of the Toba eruption on human history in previous posts (See: The Toba Super Eruption: A Global Catastrophe that... Continue Reading →
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 →
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 →
Here is a puzzle: Where can you stand on dry ground and look up to see a river channel above you? Yes, New Orleans is a good answer. However, I'm talking about looking up 100 feet from a non man-made location. There are many places on Earth and possibly on Mars where such... Continue Reading →
Phrenology, essential oils, homeopathy, reflexology, ESP, astrology, creation science, climate change denial, blood-type diet, vaccinations cause autism, quantum computing, smoking causes cancer, dinosaurs were killed by an asteroid impact, HIV causes AIDS, low-carb diet. Which of the above would you classify as the products of good scientific research and which would you classify as pseudoscience? ... Continue Reading →
Everyone is an expert in something but they can’t be an expert in everything. At some point we all have to rely on the expertise of others to guide us through our lives. I am a biologist, however, the vastness of the field of biology leaves me in the position of deferring to the knowledge... Continue Reading →
In Egypt the Nile River Valley conceals a massive canyon that once was as deep and wide as the Grand Canyon in Arizona. We have explored the origins of this lost canyon in the previous posts. We found that geologists attribute the origins of this massive canyon to the great drying up of the Mediterranean... Continue Reading →
A massive canyon lays hidden below the Nile Valley in Egypt. In Part II we looked as how this massive canyon was formed. Before we go on to look a bit deeper into this canyon and how it fits into Biblical chronology lets look at the chronological sequence of historical events—according to the consensus of geological experts—that must...
