No Trilobites are proven to be living in the present world, but one live Arthropod, the wood lice, or rolly-polly is similar. It lives under moist rocks or in wet, rotting trees. When you frighten or touch them, they quickly roll into a ball to protect themselves. If you turn your back, they rapidly unroll and run away. Our rolled Trilobite seemed to have had this same behaviour. At the time of its death, the trilobite had rolled to protect itself, but before it could unroll, it was covered by so much mud, it was buried alive. The weight of the mud now meant it could not unroll after death A significant percentage of Trilobites are found rolled - evidence of remarkably rapid fossilisation on a large scale.
Trilobites had a hard outer shell made of chitin (a tough protein) which was made stronger by deposits of the mineral calcium carbonate (chalk). The limbs and lower body of the animal seem to have had little or no mineral and have disappeared in some specimens. Very well-preserved specimens show they had hearts and kidneys as well as nervous, digestive and reproduction systems. Such perfect preservation was the result of rapid burial by a large enough volume of mud to prevent either air, or creatures, such as worms or bacteria causing degeneration of body tissues to begin.
This Trilobite is named Phacops and was found in the Devonian sedimentary rocks of Morocco in Africa. Many show well-preserved tiny eye lenses that you can sometimes see under a magnifying glass. In larger specimens these eyes are often so well-preserved you can pull the eye lens out, look through it, and see the world as trilobites did. Phacops had large eyes so it probably enjoyed 360 degree field of vision. Trilobite eyes provide remarkable evidence for creation as one author noted: "Recently, Clarkson and Levi-Setti (1975) of the University of Chicago have done some spectacular work on the optics of the trilobite eye lenses. It turns out that each lens is a doublet, that is, made up of two lenses, while the shape of the boundary between the two lenses is unlike any now in use - either by animals or humans (Shawver 1974). However, the lens shape and the interface curvature is nearly identical to designs published independently by Descartes and Huygens in the seventeenth century. Their design had the purpose of avoiding spherical aberration and were known as aplanatic lenses. Levi-Setti pointed out that the second lens in the doublet of the trilobite eye was necessary in order that the lens system could work under water where the trilobites lived. Thus, these creatures living at the earliest stages of life used an optimal lens design that would require very sophisticated optical engineering procedures to develop today."
