“…Mendes et al . (2020) showed that the structure of the Crato Formation food web has several similarities to modern food webs. Therefore, it is possible that, as for the great majority of extant Euphasmatodea, the diet of A. reliquum was composed of angiosperms.…”

Stick insects (Phasmatodea) are herbivorous, mostly nocturnal insects known for their camouflage specialization, constituting a moderately diverse group with around 3400 extant described species. The overall poor and often confusing fossil record of Phasmatodea, especially regarding older taxa, has muddled the knowledge of the early evolution of the lineage and hindered reliable calibration points for ordinal‐level phylogenies. The phylogenetic relationships within the order remain unresolved, but recent research sheds more light on the subject. Here we report on the oldest known fossil of Euphasmatodea, by revising the taxonomic identity of one fossil species (Eoproscopia reliquum Mendes, Vasconcelos & Oliveira) previously described as a stick grasshopper (family Proscopiidae). Based on the finding of a more complete specimen the taxon is redescribed and a new genus, Araripephasma, is erected to accommodate this species in Euphasmatodea. Araripephasma reliquum comb. nov. is a remarkably modern‐looking stick insect species that provides a new minimum age for Euphasmatodea and sets a good and reliable calibration point for phylogenetic and evolutionary studies. The implications of this rare finding for the evolutionary history of Phasmatodea are discussed.

Cratoaeschnidium martinsnetoi gen. et sp. nov., third genus and species of Aeschnidiidae from the Crato Formation (Brazil), is described and illustrated based on one well-preserved forewing.It can be differentiated from the other genera in the family, inter alia, because of its discoidal triangle very narrow with only one row of cells; three rows of cells between Mspl and MAa, and between Rspl and IR2; one row of cells between CuAa and MP in basal part; three rows of cells between RP3/4 and MAa. This new genus and species confirms that much can be expected in regard to discovering the Odonata in the Crato Formation.

“…According to Ribeiro et al (2021), the fossil-rich interval of the formation -the "Crato Konservat-Lagerstätte" or CKL -, consisted of a semi-arid seasonal lacustrine wetland, in which a shallow water body, including diverse aquatic fauna and flora, was succeeded up-landward by neighboring mesophytic ecotones, periodically flooded, besides outer xeric habitats. Trophic structure analysis and details of the putative food web that took place within the Crato Ecosystem are provided by Mendes et al (2020).…”

Popularly known as horse flies or deer flies, Tabanidae, has 4.400 described species distributed worldwide. Most of the females are hematophagous, but several species are also flower visitors. Cretaceous fossils of Tabanidae are scarce and the known fossil species have plesiomorphic features unknown in modern horse flies. Here, we revised the taxonomy of the Tabanidae from the Crato Formation of Brazil describing a new genus, Araripusgen. nov., and two new species – Araripus crassitibialissp. nov. and Cratotabanus cearensissp. nov. The holotype of Cratotabanus stonemyomorphus, the type species of Cratotabanus, is redescribed, and the male is described for the first time. In addition, we investigate the phylogenetic position of Cretaceous horse fly fossils using morphological characters in the context of a wider analysis also including representatives of extant lineages.
