Snowmastodon Fossil Discovery: Mastodons, Mammoths, Camels and Giant Sloths in Alpine Colorado

Near the top of a 9000-foot-high mountain ridge lies a small reservoir dug out of an alpine meadow. Today, the Ziegler Reservoir acts as a water source for the ski village of Snowmass, Colorado, but long before this site was an alpine meadow, it was an ancient lake around whose shores lived mastodons, mammoths, camels—yes […]

Permian Pompeii Challenge Taken Up? ICR’s Brian Thomas Floats a Forest Hypothesis

Recently I shared evidence of an ancient forest preserved in amazing detail by volcanic ash (An Ancient and Alien Forest Reconstructed: A challenge for young earth creationism). I posed a number of challenging questions that this spectacular fossil discovery raises for those that hold to a young-earth creationist’ (YEC) understanding of earth’s history.   Since then, […]

Ancient Rivers: The Exhumed Palaeochannels of Utah and Mars

Here is a puzzle:  Where can you stand on dry ground and look up to see a river channel above you? Ok, yes, New Orleans is a good answer.   But I’m talking about looking up 100 feet from a non man-made location.   There are a number of places on Earth and possibly on […]

Ancient Mars: Cosmogenic Dating Methods Allow Estimates of Erosion Rates on Mars

The NASA rover Curiosity has been making its way across the floor of Gale crater on Mars since 2012.  It has closely examined a wide range of rock types which reveal that this location on Mars has experienced a long history of variable climates.  From water-infused bedrock, water-deposited conglomerates, wind-formed fossilized dunes to active sand […]

A Mediterranean Island Petrified Forest: Another Monument to an Ancient Earth

On the Greek Island of Lesvos there is a World Heritage Site which includes hundreds of petrified trees and countless other fossils.  Many of these petrified trees are found standing upright with root systems intact.  A variety of tree species have been identified including a species similar to the giant sequoia trees found today in California. […]

Reflections on “Is Genesis History?” Part II: Where do the Lines of Evidence Lead?

The question posed in the title of the documentary-style film “Is Genesis History?” sounds provocative, but the answer was never in doubt in the mind of the filmmakers—or the primary audience.  The producers surely hoped that non-Christians and Christians alike with questions about origins/natural history/science would be drawn in by the title query and subtitle […]

An Ammonite Fossil Leaves A Trail of Evidence of a Tranquil Jurassic Seafloor

A remarkable trace fossil has given us a glimpse into the environmental conditions of a Jurassic seafloor.   Ammonite fossils are common in Jurassic rocks but one particular ammonite is more unusual than most.  In the horizontal layer of rock where it was found a 28 foot-long line of shallow grooves was found leading right up to the […]

Millions of Fossilized Footprints – A Global Flood Dinosaur Dilemma

Animal tracks preserved in stone are found in great abundance in many parts of the geological column.  You might be asking yourself, aren’t the chances incredibly small that any individual track made in mud would be preserved over long periods of time? You would be right.  The vast majority of footprints won’t survive the ravages of […]

A Fossil Paradox? Footprints are Rarely Preserved in Stone and yet are very Common

Billions of footprints are preserved in the rock record.  While bones get all the attention, fossil footprints likely 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 to reconstruct […]

Dinosaur Footprints, Eggs and Bones – Are Paleontologists Creating Fake History?

Dinosaur tracks and eggshells are found in great abundance in the geological column.   Many paleontologists have devoted their careers to finding, characterizing and interpreting these remains of these extinct organisms.  But is all their work to put these fossils into a historical context simply a fantasy?  If the young-earth view of earth’s history is correct, […]

A Strange Testament to an Ancient Earth: Bat Breath Causes Caves to Grow Larger

Can the act of breathing in a cave cause it to grow larger?  Limestone caves are usually formed by dissolution of limestone as the result of the interaction of carbon dioxide dissolved in water seeping through cracks in bedrock.   Typically this begins deep underground and as voids expand and reach the surface animals may enter […]

The Naica Cave of Crystals is a Giant Problem for a Young Earth

Nine hundred feet below a Mexican desert hundreds of giant white crystals, some more than 90 feet long and 13 feet wide, fill a hot (137 F) and humid cavern.  Pictures of people exploring this crystal palace look as if Rick Moranis had shrunk them down to the size of an ant and then put them into […]

A Dinosaur Tale: A Young-Earth Speaker Takes on the Asteroid Extinction Theory

What happens when a speaker gives a talk about dinosaurs but doesn’t have any training in geology or paleontology? You could get a string of distortions of both of these fields of inquiry and even problems keeping facts straight.  A few weeks ago I witnessed just such a talk when I attended an Answers in Genesis […]

Historical Science: How do We Know a Fish Fossil is a Fish Fossil?

The difference between what young earth creationists like to term “operational” or “observational” science and historical science doesn’t have the sharp distinction they like to project to their audience.  I was reminded of this recently when I had an opportunity to hear Tommy Mitchell speak at a local Answers in Genesis conference a few weeks ago.  One particular talk was […]

John Ray in 1695: The Flood, Fossils, and Extinction

John Ray, one of England’s greatest 17th century natural theologians, spent much time pondering the meaning of fossils or “formed stones” as they were called then.  I have shared some of his thoughts about fossils and Earth’s history before (See:  John Ray on Flood Geology: Words that Still Apply Today).   In a correspondence with […]
