Introduction
Works at the Paleontology Laboratory of the Universidade Federal do Espírito Santo. Research focus on taphonomy of aquatic insects from the Crato Formation Lagerstätte of Brazil.

The systematics of all known extant and fossil taxa of the mayfly family Baetiscidae is reviewed. Previously described fossil Baetiscidae are critically reviewed and their systematic position is re-evaluated. Added herein is the description of Balticobaetisca bispinata sp. nov., a new fossil mayfly from Eocene Baltic Amber. Also described for the f...
Among mayflies, the Hexagenitidae is the most common family of the Cretaceous, including in the world-renowned Crato Formation (Aptian) of northeastern Brazil. However, most of the Crato mayfly fauna was described based on nymphs, which, due to their ontogenetic development, may present numerous continuous characters. As a consequence, many unclear...
Mass mortality events are unusual in the Crato Formation. Although mayflies' accumulations have been previously reported from that unit, they lacked crucial stratigraphic data. Here we provide the first taphonomic analysis of a mayfly mass mortality event, from a layer 285 cm from the top of the Formation, with 40 larvae, and an overview of the gen...
The Crato Formation (Araripe Basin) preserves one of the most diverse entomofaunas of the Cretaceous. Among the groups of insects, mayflies stand out in abundance, but among them oligoneuriids are especially rare. A newly discovered adult oligoneuriid from this unit is here described as Incogemina nubila gen. et sp. nov. and new subfamily Incogemin...
One of the greatest obstacles to biodiversity conservation is the lack of information to prioritize efforts on practical actions. This lack of information comes mainly from absence of inventories in many areas where few groups have reasonably complete databases. The distribution of the dragonfly fauna of Brazil is little known - only 29% of the Bra...
Questions
Question (1)
I'm interested in hearing mayfly nymphs, not only on last instar (as usual for those working with association of individuals). However, I'm struggling to find methodologies. What do they eat? Do I need a pump in the aquarium? Do I need substrate?

The main aim of this project is to examine taphonomic and ecological aspects of mayflies (Ephemeroptera), dragonflies and damselflies (Odonata), using biostratinomic, actualistic, and paleometric data, from fossils of the Lower Cretaceous Crato Formation (northeast Brazil), and the Upper Jurassic Solnhofen Archipelago (southern Germany).
Among the groups of insects, the Ephemeroptera in the Crato Formation, Araripe Basin, stand out. We are describing fossil specimens recently collected, providing new morphological information about the brazilian early Cretaceous fauna. In addition, we are analyzing a mayfly mass mortality, collected in controlled excavations, the first of its kind for the Crato Formation. Relying on the morphological and taphonomic information provided by the larvae mass burial, we intend to answer climatic issues about the environment of this unit.
