Enigmatic dinosaur precursors bridge the gap to the origin of Pterosauria
Pterosaurs were the first vertebrates to evolve powered flight
1 and comprised one of the main evolutionary radiations in terrestrial ecosystems of...

The First Record of a Pteranodontid (Pterosauria, Pteranodontidae) from the Late Cretaceous of the Lower Volga Region
AbstractAn ulna fragment of a pterosaur Pteranodontidae indet. is described from the locality Polunino 2 in Volgograd Oblast (Late Cretaceous,...

New reptile shows dinosaurs and pterosaurs evolved among diverse precursors
Dinosaurs and pterosaurs have remarkable diversity and disparity through most of the Mesozoic Era
1 –3 . Soon after their origins, these reptiles...

First Articulated Rhamphorhynchoid Pterosaur from the Early Cretaceous of the Democratic People’s Republic of Korea
AbstractA nearly complete skeleton of a Mesozoic pterosaur, which probably belongs to Jeholopterus (Anurognathidae), was discovered in the third...

Functional and ecomorphological evolution of orbit shape in mesozoic archosaurs is driven by body size and diet
The orbit is one of several skull openings in the archosauromorph skull. Intuitively, it could be assumed that orbit shape would closely approximate...

A new vertebrate assemblage from the Matute Formation of the Cameros Basin (Ágreda, Spain): implications for the diversity during the Jurassic/Cretaceous boundary
The Ribota site (Ágreda, Soria, Spain) is a new locality in the Matute Formation (Tithonian–Berriasian) composed of several carbonate layers,...

A new toothless pterosaur from the Early Cretaceous Jehol Biota with comments on the Chaoyangopteridae
The Chaoyangopteridae is a clade of azhdarchoid pterosaurs that stands out in China, particularly in the Jehol Biota, as a Cretaceous group of...

Pterosaur melanosomes support signalling functions for early feathers
Remarkably well-preserved soft tissues in Mesozoic fossils have yielded substantial insights into the evolution of feathers
1 . New evidence of...

Longest-surviving Carboniferous-family insect found in Mesozoic amber
The major lineages of winged insects originated in the Carboniferous and most extant families stemmed 150 Ma later. Until now, no family from the...

Biological Evolutionary Lineages in Terrestrial Habitats in the Phanerozoic
Abiotic framework conditions of terrestrial evolution are quite different from aquatic habitats. Low density of air reduces the impacts of air...

A new pterodactyloid pterosaur with a unique filter-feeding apparatus from the Late Jurassic of Germany
A new long-legged, spatula-beaked, filter-feeding pterodactyloid pterosaur from Upper Jurassic plattenkalk limestones at Wattendorf, Bavaria,...

New insights into pterosaur cranial anatomy: X-ray imaging reveals palatal structure and evolutionary trends
Among the least studied portion of the pterosaur skeleton is the palate, which tends to be poorly preserved and commonly only visible from one side...

The absence of an invasive air sac system in the earliest dinosaurs suggests multiple origins of vertebral pneumaticity
The origin of the air sac system present in birds has been an enigma for decades. Skeletal pneumaticity related to an air sac system is present in...

Ferrodraco lentoni gen. et sp. nov., a new ornithocheirid pterosaur from the Winton Formation (Cenomanian–lower Turonian) of Queensland, Australia
The Australian pterosaur record is poor by world standards, comprising fewer than 20 fragmentary specimens. Herein, we describe the new genus and...

Dietary diversity and evolution of the earliest flying vertebrates revealed by dental microwear texture analysis
Pterosaurs, the first vertebrates to evolve active flight, lived between 210 and 66 million years ago. They were important components of Mesozoic...

Convergent evolution and convergent loss in the grasping structures of immature earwigs and aphidlion-like larvae as demonstrated by about 100-million-year-old fossils
Convergent evolution is a common phenomenon, independently leading to similar morphologies in different evolutionary lineages. Often similar...

Location-Based Management of Paleontological Collections using Open Source GIS Software
Management of Natural History collections, particularly paleontological collections, is usually structured around specimens. However, it might not be...
