What has the author E N K Clarkson written?
E. N. K. Clarkson has written: 'The evolution of the eye in trilobites' 'Environmental significance of eye-reduction in trilobites and recent arthropods'
Are dinosaurs the oldest trilobites?
No. Dinosaurs and trilobites are completely different. Trilobites were arthropods in the same phylum as insects and crustaceans. They went extinct before the first dinosaurs appeared. Dinosaurs are vertebrates and are technically classified as reptiles, though they had more in common with birds.
What is tribhites?
Trilobites are an extinct group of arthropods. They had exoskeletons, legs, and antennae. Trilobites existed from about 525 billion years ago during the Cambrian until they died out 250 million years ago, during the Permian Extinction, which wiped out about 99% of species. See the related links to learn more about trilobites.
Is a crab an arthropod?
There are 4 main groups of arthropods. They are the Chelicerata, Crustacea, Tracheata, and the now extinct Trilobites. Crabs are considered to be arthropods and are a part of the Crustacea group which also include shrimp and lobster.
What is a live anthropod?
A live anthropod would be any non-dead human. Anthropods (bipedal humans or humanoids) should not be confused with arthropods; Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages. Some arthropods are no longer living (extinct), like trilobites and the class Marrellomorpha.
What were the natural predators of trilobites?
Any carnivorous creature at that time that lived in the ocean and had a mouth big enough to eat one...they were'nt picky. The above answer is obviously far too vague and is not quite correct. Instead I offer the following: Trilobites were early relatives of the arthropods. They had ways of protecting themselves with an exoskeleton and also with spines. Evidently they were not just an available food source for whatever had a large enough mouth and happened to be hungry! Anomalocaris was one of the natural predators of the trilobites and it is also thought to be related to the arthropods. Scientists have found fossilized trilobites that have been attacked and killed by these creatures. The bite marks match perfectly with the mouth of the anomalocaris so it is apparently true.
