However, some specimens of Agnostus pisiformis were so well preserved that Mats E. Eriksson, a geology professor at Lund University, Sweden, says: "The incredible degree of preservational detail means that we can grasp the entire anatomy of the animal, which, in turn, reveals a lot about its ecology and mode of life."
Live Science suggests it looks like a space alien.
Artists have now made a copy of A. pisiformis that was only a centimetre (0.4 inches) long.
Live Science explains why the tiny sea creature is important to evolution:
“The odd little critter is also useful to modern scientists as what's called an index fossil. Index fossils are fossils that appear in only a particular time period, so they're used to date layers of rock: If the fossils appear in a rock layer, there's no question about when that layer formed.”
There is a not-so-flattering name for this kind of reasoning that is a sure way of ensuing that no one will ever find a rabbit in Cambrian strata, and evolutionists can pretend that they’re doing science.
It’s called circular reasoning.
