Introduction to Trilobites

Trilobites are arthropods with soft bodies and many legs, located under severely calcified segmented shells. They first emerged in the early Cambrian era (544 million years ago) and flourished in the middle and late Cambrian before the end of the Ordovician era (495 million years ago). They existed 49 million years ago and they diversified and created fossil records that were soon referred to by geologists. Arthropods are hard biological doors with multiple body parts and joint legs.

So, what happened to trilobites? The fossil record shows that diversity of trilobites increases as the trilobite environment changes. In this form, trilobites are expected to adapt and protect against extinction. There are many theories about the trilobite death. Many paleontologists believe that the decrease in trilobite diversity is due to an increase in predators such as squid. Since the predator fish and sharks are many after the Permits, this seem reasonable. Some researchers believe that their moulting method may also be a factor in their extinction. Brandt (1997) explained that an inconsistent suede pattern was observed in the fossil record, suggesting that it may put them at risk of injury. Contemporary crustaceans always molder with exactly the same pattern so that no limbs remain on newly molted skin. 1998)

The deployment of extinct trilobites is often controversial. One of the more new hypotheses is that the chelate filaments come from the same pair of appendages that evolved into the tentacles of Mandlulata's ancestors. Crustaceans such as crabs, lobsters, crayfish, shrimps, shrimps have long been part of the human cuisine and are currently being commercialized. Insects and their larvae are at least as nutritious as meat, can be eaten or cooked in many cultures, but not most of the culture of Europe, Hindu and Islam.
