Anderella
Extinct genus of chelicerate
From Wikipedia, the free encyclopedia
Anderella is a genus of synziphosurine,[1] a paraphyletic group of fossil chelicerate arthropods.[2][3] Anderella was regarded as part of the clade Prosomapoda.[2][4][5][6][3] Fossils of the single and type species, A. parva, have been discovered in deposits of the Carboniferous period in Montana, in the United States.[7][2] Anderella is the first[1] and so far (as of 2020) the only Carboniferous synziphosurine being described, making it the youngest member of synziphosurines.[3] Anderella is also one of the few synziphosurine genera with fossil showing evidence of appendages, but the details are obscure due to their poor preservation.[1][3]

The prosoma of Anderella possess a suboval carapace slightly longer than the externally 10-segmented opisthosoma (excluding telson).[1] A row of axial nodes run through the opisthosomal tergites.[1] The last 3 opisthosomal segments (which forming the postabdomen) are longer and lacking pleurae (lateral extensions).[1]
