Prehistoric arthropods of the Cambrian period, ... Pages in category "Cambrian arthropods" The following 103 pages are in this category, out of 103 total.
This list contains many extinct arthropod genera from the Cambrian Period of the Paleozoic Era. Some trilobites, bradoriids and phosphatocopines may not be included due to the lack of literature on these clades and inaccessibility of many papers describing their genera. This list also provides references for any Wikipedia users who intend to ...
Opabinia regalis is an extinct, stem group arthropod found in the Middle Cambrian Burgess Shale Lagerstätte (505 million years ago) of British Columbia. [1] Opabinia was a soft-bodied animal, measuring up to 7 cm in body length, and had a segmented trunk with flaps along its sides and a fan-shaped tail.
Trilobite development was unusual in the way in which articulations developed between segments, and changes in the development of articulation gave rise to the conventionally recognized developmental phases of the trilobite life cycle (divided into three stages), which are not readily-comparable with those of other arthropods.
The Cambrian explosion was a period of rapid multicellular growth. Most animal life during the Cambrian was aquatic. Trilobites were once assumed to be the dominant life form at that time, [57] but this has proven to be incorrect. Arthropods were by far the most dominant animals in the ocean, but trilobites were only a minor part of the total ...
It also presents the possibility that bivalved arthropods were very diverse, and filled in a lot of ecological niches. [ 1 ] [ 2 ] [ 3 ] The hymenocarines were an order of primitive mandibulates , the arthropod group that includes crustaceans , insects , myriapods and their relatives, that lived throughout the Cambrian period.

The first occurrence of Treptichnus pedum marks the Cambrian-Ediacaran boundary in Newfoundland, although there are several occurrences some metres below.. The opening of the Cambrian period is marked by a number of biological changes, including the extinction of the Ediacara biota, the preponderance of armoured organisms (e.g. the small shelly fossils), and a "widening of the behavioural ...
Dinocaridida [derivation 1] is a proposed fossil taxon of basal arthropods, [3] which flourished during the Cambrian period and survived up to Early Devonian.Characterized by a pair of frontal appendages and series of body flaps, the name of Dinocaridids (Greek for deinos "terrible" and Latin for caris "crab") refers to the suggested role of some of these members as the largest marine ...
