Sea Lilies – Another Explosion

The "Cambrian explosion" is a term used to describe the abrupt appearance in the fossil record of major animal phyla, without intermediate forms in lower layers. This pattern of abrupt appearance can be observed for many groups of organisms, including crinoids (sea lilies).

An Amphibious Whale or a Terrestrial Swimmer?

Is a recent fossil found in Peru evidence for transitional forms in an evolutionary sequence?

Trilobite Explosion

The abrupt appearance of trilobites in Cambrian strata and their absence in Precambrian sediments is a real feature of the rock record and not due to failure of preservation in Precambrian rocks.

Modern Bird Lung Design Documented in Rapidly Buried Fossil

A fossil bird recovered from Cretaceous lake deposits in China shows preservation of some soft tissues, including a pair of lungs that appear to have functioned in a way similar to those of living birds.

A Chemist's Perspective of the Yellowstone Petrified “Forests"

The Yellowstone "fossil forest" has many layers of volcanic ash. Trace element analysis of these layers reveals they derive from about four volcanic sources, and the layers from different sources are interlaced, implying contemporaneous eruptions of the different sources. Published in Origins n. 65.

The Explanation for the “Yellowstone Fossil Forests:” An Uncompleted Research Project

An appeal, by Dr. Leonard Brand, for more original research, publications, and review papers to present a coherent model for the interpretation of the Yellowstone fossil forests that would bring it to the attention of the geological community. Published in Origins n. 65.

Pterosaurs of the Triassic: An Update

This post complements an article that was written in 2014. Since then, there have been some interesting developments in the area of Triassic pterosaurs that are worth mentioning, the most important being the recent description by Britt et al. (2018) of a Triassic pterosaur from the Nugget Sandstone of Utah.

Is There Biological Evidence of Life's Recent Creation?

During one of my frequent visits to the office of my high school headmaster, his individual tutelage yielded a life lesson that I’ve never forgotten. His exact words were, “You think you’re right!” Of course I thought I was right, wouldn’t anyone who thought they were wrong change their mind and then immediately think they are right? Now that I’m an adult biologist, I still think that I’m right. Inevitably…

Archaeopteryx: Bird or Reptile? Or Not?

Archaeopteryx is arguably the most famous fossil ever discovered. It has a mixture of bird-like and reptile-like traits, and was first reported only two years after Charles Darwin published his book, The Origin of Species. Since then, another eleven Archaeopteryx specimens have been recovered from the limestones near Solnhofen, Germany.

Preservation of Dinosaur Soft Tissue: An Update

“You are dust, and to dust you shall return.” This verse from Genesis 3 captures very well the fate of beautifully designed organisms after the entrance of sin into the world. But how long does it take for the organic molecules we are made of to break down after death? In general, the longer the time from death, the larger the amount of decay that should be observed. This is particularly true for soft…

Homo naledi: An update

Two important papers were published in May 2017, warranting an update on the subject of Homo naledi.

What Is the Evidence for a Large Asteroid Impact at the Cretaceous-Paleogene (K-Pg) Boundary?

The hypothesis of a large meteorite impacting the surface of the Earth at the end of the Cretaceous was introduced almost four decades ago. In the ensuing years, the geologic community gathered a large body of data in support of this hypothesis, elevating it to the status of a universally accepted fact of Earth history. However, competing models and lively discussions are still unfolding over the dynamics and environmental consequences of this large impact.

A Review of the Documentary Film “Is Genesis History?”

Is Genesis History? asks a question that many Christians struggle with. Is the first book of the Bible comprised of pious myths? Is it an allegory designed to teach important lessons about God, but not actually a record of the history of life on Earth? Or is it a reliable record of events that actually occurred in the past? In other words, is Genesis the oldest book of history available today, one…

The Mesozoic

Few things in science evoke more interest in children than dinosaurs. Books, films, toys, etc. continue to fuel kids’ interest in the very alien world of our past, yet few Christians know how to respond to their children’s curiosity in a way that is both biblically sound and scientifically accurate. Although a full discussion of the fossils in Mesozoic rocks would require several volumes, a brief synopsis is presented here along with some creationist reflections for those who are interested – parents or otherwise.

Is Homo naledi Your “Relative,” “Ancestor,” or “Part of the Human Family Tree”?

The aim of this article is to use the example of Homo naledi to illustrate the distinction between data and interpretations, and to discuss some of the questions a biblical creationist might have in relation to this new discovery.

Pterosaurs of the Triassic

There are only three known groups of volant vertebrates. Two are extant: birds and bats. The third group is completely extinct and known only from fossils: pterosaurs. Often referred to colloquially as “pterodactyls”, pterosaurs are a diverse group of reptiles totally foreign to our modern minds, yet in some ways they are incredibly familiar, resembling the dragons of folklore.

Dinosaurs and the Bible

Is it possible to study the dinosaurs (and other fossils) from a perspective consistent with the biblical account of creation?
