Crustacean - Evolution, Paleontology, Adaptations | Britannica
2024年11月8日 · Crustacean - Evolution, Paleontology, Adaptations: The evolution of crustaceans can be studied with two approaches: interpretation of evidence from comparative anatomy, or consideration of the fossil record. The earliest of the definite fossil crustaceans are ostracods; a decapod occurs in the Devonian.
Crustacean - Wikipedia
Most crustaceans are free-living aquatic animals, but some are terrestrial (e.g. woodlice, sandhoppers), some are parasitic (e.g. Rhizocephala, fish lice, tongue worms) and some are sessile (e.g. barnacles). The group has an extensive fossil record, reaching back to the Cambrian.
(PDF) The Fossil Record of the Pancrustacea - ResearchGate
2020年9月10日 · We review the systematics, morphology, preservation, and paleoecology of pancrustacean fossils; each major clade is discussed in turn, and, where possible, fossil systematics are compared with...
The Fossil Record of the Clam Shrimp (Crustacea; Branchiopoda)
Clam shrimp (the paraphyletic assemblage of spinicaudatans, laevicaudatans, cyclestherids and the extinct leaiins) are small, bivalved branchiopod crustaceans that specialize in ephemeral freshwater habitats. They have a long fossil record (Devonian onward) …
The fossil record of the Cladocera (Crustacea: Branchiopoda): Evidence ...
2016年12月1日 · Here we present a critical review of the complete fossil record of the Cladocera including the first ever deep-time palaeolimnological framework for the group. Cladocera are key primary consumers whose evolution is crucial to the understanding of the Mesozoic Lacustrine Revolution that helped to shape aquatic ecosystems.
crusty systematics - University of California Museum of Paleontology
Crustaceans are classified by the form of their body, the number of segments they possess, the presence or absence of a carapace, and the shape and function of their appendages. Most living and post-Cambrian fossil crustaceans fall into one of five groups, shown above.
(PDF) A Modern Overview of Crustacean Biogeography
2021年11月24日 · The evolutionary history of arthropods is illuminated by a rich record of fossils, often with exquisite preservation, but current analyses conflict over whether certain fossil groups are stem-...
3 Evolution and Radiation of Crustacea - Oxford Academic
The early crustacean fossil record (especially the Ordovician) is dominated by ostracods. Malacostracans, although having Cambrian origins, did not significantly radiate until the Mesozoic. Eumalacostraca continued to actively radiate in the Cenozoic and are now the most ubiquitous and morphologically disparate crustaceans.
A phylogeny of recent and fossil Crustacea derived from
Crustaceans exhibit enormous diversity and morphological plasticity, having evolved many distinctive morphotypes with many heteronomous character combinations since their origination in the Cambrian (Schram, 1982; Briggs, 1992).
Toward a Global Phylogeny of the “Living Fossil" Crustacean
2012年4月18日 · Tadpole shrimp (Crustacea, Notostraca) are iconic inhabitants of temporary aquatic habitats worldwide. Often cited as prime examples of evolutionary stasis, surviving representatives closely resemble fossils older than 200 mya, suggestive of an ancient origin.
