New record of Mastotermitidae from Fonseca Basin, Eocene-Oligocene boundary of ...
Bezerra, Francisco Irineudo; Mendes, Márcio; Souza, Og deThe first representative of the genus Mastotermes Froggatt, 1897 from the Cenozoic of the South America is described here based on seven specimens from the Fonseca Formation, Eocene-Oligocene boundary, Minas Gerais State, southeastern Brazil. Today, Mastotermes is geographically restricted to northern Australia, with only one relict species, Mastotermes darwiniensis Froggatt, 1897. However, its fossil record cl...
A new primitive termite (Isoptera) from the Crato Formation, Araripe Basin, Ear...
Bezerra, Francisco Irineudo; Souza, Og de; Ribeiro, Guilherme Cunha; Mendes, MárcioMeiatermes cretacicus n. sp., an alate termite from the Early Cretaceous Crato Formation, Araripe Basin, northeastern Brazil. The new taxon is similar in many characteristics to other termites from the Araripe Basin, and primitive termites from Spanish amber. The rounded head and pronotum, Y-shaped line, veins Sc, R, Rs and M more heavily sclerotized than CuA, multiple Rs branches, and CuA well-developed are fe...
Distinct preservational pathways of insects from the Crato Formation, Lower Cre...
Bezerra, Francisco Irineudo; Solórzano-Kraemer, Mónica M.; Mendes, MárcioThis study compares two different preservation pathways of fossil insects in the lacustrine deposits of the Crato Formation, Lower Cretaceous (Aptian) of the Araripe Basin, northeastern Brazil. Three hundred seventy-seven specimens were examined and separated into ten taxonomic groups. Of this total, one hundred twenty-three are kerogenized insects, and two hundred fifty-four are pyritized insects. We carried o...
Chemical and mineral comparison of fossil insect cuticles from Crato Konservat ...
Bezerra, Francisco Irineudo; Silva, João H. da; Miguel, Emílio de Castro; Paschoal, Alexandre Rocha; Nascimento Júnior, Daniel Rodrigues doThe Crato Formation palaeoentomofauna from the Lower Cretaceous (Aptian) of northeast Brazil is extremely well preserved. Crato insects are often complete with abdomen, thorax, head, legs, wings articulated and fragile cuticle details observed at the macro and micro scale. The Crato Formation stands out for the high diversity of fossil insects with at least 386 described species, so far. We investigate the pres...
Throwing light on an uncommon preservation of blattodea from the Crato formatio...
Bezerra, Francisco Irineudo; Silva, João Hermínio da; Paula, Amauri Jardim de; Oliveira, Naiara Cipriano; Paschoal, Alexandre RochaFossilization results from several physical-chemical-geological processes. Original labile and non-bioclastic structures rarely survive throughout this process. In particular, the Crato Formation (Araripe Basin) is one of the most significant Cretaceous KonservatLagerstätten due to its well-preserved invertebrates, mainly three-dimensional insects. In general, Crato insects exhibit brown-orange color, constitut...
A new cheirolepidiaceous conifer Pseudofrenelopsis salesii sp. nov. from the Ea...
Batista, Maria Edenilce P.; Kunzmann, Lutz; Bezerra, Francisco Irineudo; Andrade, José Artur F. G. de; Sá, Artur A.; Loiola, Maria Iracema B.Pseudofrenelopsis is a genus of the conifer family Cheirolepidiaceae, whose temporal distribution was restricted to the Early Cretaceous. Its set of features correspond to adaptive responses to rather unstable and stressful environ- mental conditions, such as aridity and/or groundwater salinity. In this paper, we describe Pseudofrenelopsis salesii sp. nov. from the Albian Romualdo Formation of the Araripe Basin...
