“…Amino acid results place this perplexing decapod with Sergestidae (pelagic shrimp), as suggested by morphological analysis, especially spermatophore morphology [51,52]. Crown dendrobranchiates diverged in the Late Devonian (Figure 3), with the two main clades Sergestoidea and Penaeoidea both diverging in the Pennsylvanian (about 73 Myr prior to the estimates of Ma et al [53], and over 100 Myr older than the minimum ages suggested by Robalino et al [54]). Although our mean posterior age of crown Penaeidae (134 Ma) is younger than the phylogenetically justified Late Jurassic crown fossil Antrimpos speciosus [54], which we did not use as a calibration, our 95% CI encompasses the fossil age of 151 Ma.…”

Comprising over 15,000 living species, decapods (crabs, shrimp, and lobsters) are the most instantly recognizable crustaceans, representing a considerable global food source. Although decapod systematics have received much study, limitations of morphological and Sanger sequence data have yet to produce a consensus for higher-level relationships. Here we introduce a new anchored hybrid enrichment kit for decapod phylogenetics designed from genomic and transcriptomic sequences that we used to capture new high-throughput sequence data from 94 species, including 58 of 179 extant decapod families, and 11 of 12 major lineages. The enrichment kit yields 410 loci (>86,000 bp) conserved across all lineages of Decapoda, eight times more molecular data than any prior study. Phylogenomic analyses recover a robust decapod tree of life strongly supporting the monophyly of all infraorders, and monophyly of each of the reptant, 'lobster', and 'crab' groups, with some results supporting pleocyemate monophyly. We show that crown decapods diverged in the Late Ordovician and most crown lineages diverged in the Triassic-Jurassic, highlighting a cryptic Paleozoic history, and postextinction diversification. New insights into decapod relationships provide a phylogenomic window into morphology and behavior, and a basis to rapidly and cheaply expand sampling in this economically and ecologically significant invertebrate clade. Introduction:Decapod crustaceans, broadly categorized into 'shrimp', 'lobsters', and 'crabs', are embedded in the public consciousness due to their importance as a global food source worth over $24 billion [1]. Several ornamental species are also popular in the pet trade [2,3], and some lobsters and crayfish may be promising models for cancer and aging research [4]. Furthermore, decapods are a major faunal component of a bewildering variety of global habitats, including the open ocean, seafloor vents and seeps, caves, coral reefs, mangroves and estuaries, intertidal mud and sand, freshwater streams and lakes, semi-terrestrial locations, and in symbiosis with other animals (Figure 1). Decapods have diversified over the course of 455 million years resulting in over 15,000 living and 3,000 fossil species recognized in approximately 233 families [5,6]. Despite the economic and ecological significance of the clade, higher-level phylogenetic relationships among decapods have proven recalcitrant.The majority of work is restricted to studies using morphology [7][8][9], up to nine targeted mitochondrial and nuclear genes [6,[10][11][12][13][14][15][16][17][18][19], and more recently complete mitogenomes of 13 genes [20][21][22][23][24]. Mitogenomic data can be problematic for reconstructing ancient nodes [25], and indeed, deeper relationships receive poor support [24]. As part of a larger analysis, decapods were included in a recent transcriptomic study [26], but with limited taxon sampling within the order. This plurality of results, several based on the same underlying data [25], have reported conflicting deep relationshi...

“…As it was outside of Sergia + Deosergestes, and we did not sample Acetes, we allow P. deliciosa to calibrate the clade including Lucifer. Note that a likely member of Luciferidae was recently discovered from the same deposits [53], and could be appropriate for this node as well.…”

“…However, the fossils from the Araripe Basin are very well known for their excellent state of preservation and paleobiological diversity (Martill, 1988). On the other hand, the knowledge about fossil shrimp in the Araripe Basin is basically restricted to taxonomic works (Martins-Neto & Mezzalira, 1991a; Martins-Neto & Mezzalira, 1991b; Maisey & Carvalho, 1995; Santana et al, 2013; Pinheiro, Saraiva & Santana, 2014; Saraiva, Pinheiro & Santana, 2018).…”

The Ipubi and Romualdo Formations are Cretaceous units of the Araripe Basin (Santana Group). The first and most ancient was deposited in a lake environment, and some fossils were preserved in shales deposited under blackish conditions. The second was deposited in a marine environment, preserving a rich paleontological content in calcareous concretions. Considering that these two environments preserved their fossils under different processes, in this work we investigated the chemical composition of two fossilized specimens, one from each of the studied stratigraphic units, and compared them using vibrational spectroscopy techniques (Raman and IR), X-ray diffraction and large-field energy-dispersive X-ray spectroscopy (EDS) mappings. Calcite was observed as the dominant phase and carbon was observed in the fossils as a byproduct of the decomposition. The preservation of hydroxide calcium phosphate (Ca10(PO4)6(OH)2, hydroxyapatite) was observed in both fossils. In addition, it was observed that there was a smaller amount of pyrite (pyritization) in the Romualdo Formation sample than in the Ipubi one. Large-field EDS measurements showed the major presence of the chemical elements calcium, oxygen, iron, aluminum and fluoride in the Ipubi fossil, indicating a greater influence of inorganic processes in its fossilization. Our results also suggest that the Romualdo Formation fossilization process involved the substitution of the hydroxyl group by fluorine, providing durability to the fossils.

“…As primeiras publicações datam dos anos de 1940 e 1950, e entre este último e o ano de 1990 inexistem trabalhos na literatura. O interesse pelos fósseis desses crustáceos tornou-se mais frequente a partir da primeira década do século XXI, com os trabalhos de Alencar et al (2018Alencar et al ( , 2020; Pinheiro et al (2014); Prado, Calado & Barreto (2019); Santana et al (2013); Saraiva et al (2018). O que foi possível devido à realização de coletas sistemáticas nas formações Crato e Romualdo, da Bacia do Araripe, evidenciando a potencialidade paleontológica desses invertebrados nos afloramentos cretácicos da região, em particular àqueles localizados no estado do Ceará.…”

Este trabalho apresenta o estado da arte acerca do estudo com camarões fósseis encontrados em bacias sedimentares brasileiras, pontuando as ocorrências no espaço e no tempo geológico. O registro de camarões fósseis no Brasil restringe-se às bacias do Tucano (Formação Marizal -Aptiano), do Araripe (Formações Crato, Ipubi e Romualdo -Aptiano) e Taubaté (Formação Tremembé -Oligoceno). Ao longo de 80 anos, desde os primeiros achados no ano de 1940, foram descritas doze espécies com idades entre o Cretáceo Inferior e o Paleógeno, todas oriundas de sistemas aquáticos com diferentes níveis de salinidade e estresse hídrico. Espera-se que os dados aqui reunidos e apresentados possam constituir uma ferramenta de estímulo às pesquisas futuras, uma vez que sumariza informações preciosas sobre estes indivíduos fósseis.
