Abstract Many studies have improved our understanding of the mode preservation at Crato fossil Lagerstätte . The high degree mineralized insects is thought to be a consequence diffusion ions through carcasses and envelopment by bacteria that, in turn, created microenvironmental conditions that led mineralization, mainly pyritization. Pyritized been oxidized situ weathering more stable oxide/hydroxy minerals during Quaternary time. This transformation essential maintain palaeontological...
Fossilization 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 most significant Cretaceous Konservat-Lagerstätten due to its well-preserved invertebrates, mainly three-dimensional insects.In general, insects exhibit brown-orange color, constituted by goethite or hematite replacements.In context, we used scanning electron microscopy...
This paper records the first occurrence of genus Myrmicium Westwood, 1854 in Cretaceous Gondwana and describes it as a new species araripterum sp. nov, based on most complete specimen this yet known, which represents largest grade “Symphyta” ever found Crato Formation.
A new specimen of a stick grasshopper (Orthoptera: Proscopioidea: Proscopiidae) is described from the Early Cretaceous (Late Aptian – Albian) Crato Formation southern Ceará, northeastern Brazil. This only second formal description Proscopiidae in fossil Record. Unfortunately, LP/UFC CRT 2698 poorly preserved as faint impression due to post-diagenetic processes. However, discovery this taxon enhances diversity Gondwana, and it confirms South America dispersion zone for family.
ABSTRACT The Fonseca Formation (Eocene–Oligocene boundary, Minas Gerais, Brazil) is well known for its paleoflora, especially of flowering plants. richness this insect-bearing fossil locality significantly less understood, but we can shed light on the insect paleocommunity. One hundred and eight specimens were examined separated into four grades based their preservational quality. We conducted analyses taphonomic features, including body orientation, size, articulation, chemical composition....
Chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), has affected amphibians globally since 1970s, being considered main cause of their decline worldwide. The present study is first to assess presence Bd in anuran populations dry and wet tropical forests Ceará state, northeastern Brazil. Samples were collected different environmental landscapes throughout dominant Caatinga relict moist forest (brejos de altitude) localities Monte Alegre Private Natural Heritage...
Fossil whip scorpions (Thelyphonida) are extremely rare in the Crato Formation strata, Araripe Basin, Lower Cretaceous (Aptian) of Brazil. Only four specimens have been described this unit so far. All assigned to genus Mesoproctus Dunlop and only one species has formally proposed, M. rowlandi Dunlop. For Mesozoic times, apart from Formation, documented by two amber deposits Hukawng Valley, northern Myanmar. In scenario, each new discovery scorpion is highly important. addition, we present...
