|---|---|---|---|
This list of fossil arthropods described in 2019 is a list of new taxa of trilobites, fossil insects, crustaceans, arachnids and other fossil arthropods of every kind that are scheduled to be described during the year 2019, as well as other significant discoveries and events related to arthropod paleontology that are scheduled to occur in the year 2019.
General research
[edit]- A revision of higher-level arthropod taxonomy is published by Aria (2019), who proposes the name Cenocondyla for the least inclusive group containing both Mandibulata and Chelicerata.[1]
- A study on the molecular composition and microanatomy of the eyes of 54-million-year-old crane flies from the Fur Formation (Denmark), evaluating its implications for the knowledge of optical systems of other ancient arthropods (especially trilobites), is published by Lindgren et al. (2019).[2]
Arachnids
[edit]Research
[edit]- Two new specimens of laniatorid harvestmen (an adult specimen assignable to the species Proholoscotolemon nemastomoides and a smaller specimen belonging or related to the genus Proholoscotolemon) are described from the Eocene Baltic amber by Bartel & Dunlop (2019).[3]
- A review of the phylogenetic hypotheses of scorpion interrelationships, as well as of scorpion palaeontology, is published by Howard et al. (2019), who also provide a list of scorpion fossil calibrations for use in molecular dating.[4]
- A fossil spider, possibly a juvenile female golden silk orb-weaver, is described from the Lower Eocene Palana Formation of the Gurha opencast lignite mine (western Rajasthan, India) by Patel, Rana & Selden (2019), representing the first fossil spider from India which wasn't found in amber.[5]
- A review of the fossil record and evolutionary history of spiders, reevaluating the phylogenetic placement of key fossils and aiming to determine whether there has been a major turnover in the spider fauna between the Mesozoic and Cenozoic, is published online by Magalhaes et al. (2019).[6]

[edit]Trilobites
[edit]Research
[edit]- A study on the rates of evolution of trilobites in the Cambrian is published by Paterson, Edgecombe & Lee (2019), who interpret their findings as indicative of Cambrian rather than Precambrian origin of trilobites, and as indicating that the Cambrian explosion had already largely concluded by the time the typical Cambrian fossil record begins (≈521 Ma).[113]
- A study on repaired injuries in trilobite specimens from the Cambrian Ruin Wash Lagerstätte (Nevada, United States) is published by Pates & Bicknell (2019), who interpret their findings as indicative of species specific predation on Cambrian trilobites, and of enlarged spines in some trilobite species serving as possible predation deterrents.[114]
- A study on the morphology and ontogeny of Changaspis elongata, based on data from specimens from the Lazizhai section of the Balang Formation (Cambrian Stage 4; Guizhou, China), is published by Du et al. (2019).[115]
- A cluster of over 100 juvenile trilobites belonging to the genus Aphelaspis is reported from the Cambrian (Paibian) Conasauga Formation (Georgia, United States) by Schwimmer & Montante (2019).[116]
- A study on patterns of occupancy and diversity trajectories in late Cambrian-early Ordovician trilobite communities from the Argentine Cordillera Oriental is published by Serra, Balseiro & Waisfeld (2019).[117]
- A study on the phylogenetic relationships of members of the family Olenidae is published by Monti & Confalonieri (2019).[118]
- A study on the phylogenetic relationships of members of the olenid subfamily Balnibarbiinae is published by Hopkins (2019).[119]
- Nine specimens of Symphysurus ebbestadi preserving all key stages of the exoskeleton moulting process are described from the Lower Ordovician Fezouata Formation (Morocco) by Drage et al. (2019).[120]
- A study on clusters of Ampyx priscus from the Ordovician Fezouata Shale of Morocco is published by Vannier et al. (2019), who interpret these clusters as evidence of a collective behaviour rather than a result of passive transportation and accumulation.[121]
- A study on the phylogenetic relationships of the species and subspecies assigned to the phacopid genus Austerops is published by Oudot et al. (2019).[122]
- A study on the morphological changes in the ontogeny of the Ordovician phacopid trilobite Calyptaulax strasburgensis is published by Jacobs & Carlucci (2019).[123]
- A well-preserved body cluster of 18 specimens of Arctinurus boltoni is described from the Silurian Rochester Shale (New York, United States) by Bicknell, Paterson & Hopkins (2019).[124]
- A study on development and evolution of the cephalon and the pygidium in phacopid trilobites is published by Oudot et al. (2019).[125]
- A study on the internal structures of eyes of trilobites belonging to the genera Asaphus and Archegonus is published by Scholtz, Staude & Dunlop (2019);[126] the study is subsequently criticized by Schoenemann & Clarkson (2021).[127][128]
