Conspectus The chemical study of materials from natural history and cultural heritage, which
provide information for art history, archeology, or paleontology, presents a series of specific …

Abstract The Crato Formation paleoentomofauna is noticeable for its high abundance,
diversity and morphological fidelity, so the preservational approach of the Ephemeroptera …

The insect fossils recorded in the lithographic limestones of the Crato Formation (Aptian of
the Araripe Basin, Brazil) have a high degree of morphological fidelity of external and …

The fossil record of non‐biomineralizing, soft‐bodied taxa is our only direct evidence of the
early history of vertebrates. A robust reconstruction of the affinities of these taxa is critical to …

Many studies have improved our understanding of the mode of preservation at the Crato
fossil Lagerstätte. The high degree of preservation of the Crato mineralized insects is …

The Crato Formation (Lower Cretaceous, Brazil) is a Konservat-Lagerstätte preserving a
great number of exceptionally well-preserved insects. Here, we sought to explore the …

This study is the first contribution towards the estimation of paleoatmospheric carbon dioxide
concentration (pCO 2) from the paleoequatorial late Aptian Crato Formation (Santana …

Microvibration induced by natural disturbance and human activities has an adverse effect on
the operation of the large-scale and ultraprecise facilities in the world. Under such …

This work presents the development of a macro X-ray fluorescence (MA-XRF) scanner
system for in situ analysis of paintings. The instrument was developed to operate using …

Fossil footprints are generally recognized by morphological features from the feet registered
on the unconsolidated substrate; therefore, they can also be understood as biogenic primary …
