Concretions are remarkable geological curiosities. They are spherical carbonate formations composed of mineral cement. Concretions are found near and far, from Western Kazakhstan to beaches in California. Usually the size of cannonballs, they form from water eroding a piece out of sedimentary rock. They almost look man-made.

Trilobites (a type of arthropod) appear in sedimentary rocks as part of the Cambrian Explosion.¹ In this episode, all the major animal groups first appear as fossils. They appear suddenly, fully-formed, and functional, and the older rock layers below them contain no ancestors.^2,3

Many environmentalists are concerned with the anthropogenic production of carbon dioxide produced by burning fossil fuels. Research projects are being funded across the globe to find ways to sequester the “extra” CO2 produced by these processes in an effort to save our planet.

ICR scientists have long pointed out that fossils, contrary to popular misperception, do not provide evidence for evolution, and a recent secular dinosaur study confirms this.¹
