Slab and counterslab of the Europejara holotype

Europejara is a genus of tapejarid pterosaur that lived during the Barremian age of the Early Cretaceous epoch in what is now Spain. The only known specimen was found at the La Huérguina Formation of Cuenca, a location noted for its exceptional Konservat-Lagerstätte preservation. In 2012, the new genus and species Europejara olcadesorum was named based on it. The holotype specimen consists of an incomplete, crushed skull (pictured); the bones of the postorbital region are displaced while the mandible is almost complete. The first tapejarid known from Europe, Europejara was also the oldest known member of that group and the oldest known toothless pterosaur at the time of its naming. Researchers have found Europejara to be related to Brazilian tapejarids and, given its age, have used this relationship as evidence for the group's origin on the northern palaeocontinent of Laurasia. Due to the shape of their jaws and skulls, they are believed to have been fruit or seed eaters. (Full article...)

African blue flycatcher

The African blue flycatcher (Elminia longicauda) is a small passerine bird in the family Stenostiridae, found in parts of West, Central and East Africa. Measuring 15 to 18 centimetres (5.9 to 7.1 in) in length, it has bright blue upperparts, a short crest, a long tail, and pale greyish-blue underparts. Its black flight feathers are edged with blue, while juveniles have duller plumage. The species inhabits forests, moist savannas, gardens and wooded farmland, foraging among leaves with its tail fanned and wings partly spread. Its song consists of a series of slow and irregular sibilant notes. This African blue flycatcher was photographed in Kibale National Park in western Uganda.
