But such rapid depositions do not fit well with the story often told by evolutionists that fossils, and the rock layers around them, are a record of slow and gradual processes. Such conditions were readily available during the Noahic Flood some 4,500 years ago. For this soft tissue to become fossilized in the limestone, it required rapid burial under a wave of lime-rich sediment. This suggests it had not long been separated before it was buried. The remains were also coiled, maintaining the spiral structure it had when attached to its shell. This is because soft tissue rapidly decays, or is normally quickly consumed by other sea-dwelling animals. Examples of soft body fossilization such as this ammonite are problematic for secular long-age (‘slow and gradual’) geology. Regardless of how it became detached, the much larger question is how it came to be fossilized. However, they are also wholly consistent with, and somewhat expected from, biblical history. Such finds are spectacular for biblical creationists, too. Of course, the internal body may also have become detached in the turbulent waters of the Noahic Flood if its shell was smashed against other items in the flowing waters. Some supporting evidence put forward for this was that it is missing its tentacles, which may have been bitten off. Ripped offĪnother proposal was that an attacking predator ripped out the internal parts before dropping them. Both the shell and soft body of ammonites are very similar to the living nautilus, in which the latter is firmly attached to the shell and cannot just ‘pop out’.

One possible explanation was that as the ammonite died the tissues connecting its soft body to the shell decayed and it fell out. The team put forward a number of different proposals to explain how the internal body became separated from its shell. This included the esophagus, stomach, intestines, central nervous system, reproductive organs, and eye capsules. After examination under a range of different lights, the researchers were able to identify a number of organs. It was identified as an ammonite from its shelly lower jaw. 2 The body was not connected to its shell. What Clements is referring to is the extraordinarily well preserved internal soft body of an ammonite located in Germany’s Solnhofen limestone deposit. “It’s like finding … well, I don’t even know what it’s like finding, it’s that bizarre.” 1 … the extraordinarily well preserved internal soft body of an ammonite located in Germany’s Solnhofen limestone deposit. “We know millions and millions of ammonites that have been preserved from their shell, so something exceptional had to happen here,” said Thomas Clements, a paleobiologist at the University of Birmingham, England. However, remains of the animal that was housed inside the shell are exceedingly rare.
