Even more like birds Ecological convergence between pterosaurs and birds is often invoked, but to what degree the two groups share behavior is debated. Wang et al. describe a site with more than 100 fossilized pterosaur eggs that reveals that hatchling pterosaurs were likely not as precocial as previously thought (see the Perspective by Deeming). Furthermore, the overlaying of multiple clutches suggests that the pterosaurs may have exhibited breeding site fidelity, similar to rookery-breeding… 
Prenatal development in pterosaurs and its implications for their postnatal locomotory ability
TLDR
Early ossification of the vertebral column, limb girdles and principal limb bones involved some heterochronic shifts in appearance times and facilitated full development of the flight apparatus prior to hatching, consistent with a super-precocial flight ability and suggests that it was not an absolute requirement.

TLDR
Wang et al. (3) report the largest accumulation of Hamipterus pterosaur eggs found to date, which is a crucial advance in understanding pterOSaur reproduction.
The first dinosaur egg was soft
TLDR
Molecular analyses of newly discovered, embryo-bearing ornithischian and sauropod dinosaur eggs suggest that the ancestral dinosaur egg was soft- shelled, and that hard-shelled eggs evolved independently at least three times in the major dinosaur lineages.
The Evolutionary Developmental Control of the Avian Feeding Apparatus
TLDR
It is suggested that several molecules regulating the development of the avian beak also mediate the growth of keratinous rhamphothecae, and the divergence of odontogenic signalling pathways are likely to have accounted for both of these processes.
The diverse terminology of reptile eggshell microstructure and its effect on phylogenetic comparative analyses
TLDR
It is concluded that the traditional “soft/hard/semi‐rigid” classification of reptilian eggshells should be abandoned and guidelines for future descriptions focusing on specific functionally relevant characteristics are provided.
New information on multispherulitic dinosaur eggs: Faveoloolithidae and Dendroolithidae
TLDR
This work provides the first experimental evidence that some mid-sized dendroolithid eggs were laid by a therizinosauroid theropod, and scans and studied two faveoloolithid eggs.
Pelvis morphology suggests that early Mesozoic birds were too heavy to contact incubate their eggs
TLDR
The indirect approach provides the best evidence yet that early birds could not have sat on their eggs without running the risk of causing damage and suggests that contact incubation evolved comparatively late in birds.
Microstructural description of the maniraptoran egg Protoceratopsidovum
Since their discovery in the 1920s, some asymmetric, elongated dinosaur eggs from the Upper Cretaceous of Mongolia have been interpreted as ceratopsian eggs. However, recent views support a
A new wing skeleton of the Jehol tapejarid Sinopterus and its implications for ontogeny and paleoecology of the Tapejaridae
The tapejarid pterosaurs flourished in the Jehol Biota with an abundance of immature individuals and a rarity of individuals at skeletal maturity. Most of these individuals plot well on an

Pterosaur eggshell structure and its implications for pterosaur reproductive biology
TLDR
It seems unlikely that the parchment-shelled eggs of pterosaurs were incubated by direct contact with the body of a parent because of the risk of crushing the egg, and they are likely to have developed in a thermal environment close to ambient temperatures and probably subject to some temperature variation.
Eggshell and Histology Provide Insight on the Life History of a Pterosaur with Two Functional Ovaries.
TLDR
Pterosaurs laid eggs even smaller than previously thought and had a reproductive strategy more similar to basal reptiles than to birds, which shows that pterosaurs were highly precocial or needed parental care.
Developmental growth patterns of the filter-feeder pterosaur, Pterodaustro guiñazui
TLDR
A comprehensive osteohistological assessment of multiple skeletal elements of a range of ontogenetic sizes of Pterodaustro is presented, and unparalleled insight is provided into its growth dynamics.
Sauropod dinosaur embryos from the Late Cretaceous of Patagonia
TLDR
The first known unequivocal embryonic remains of sauropod dinosaurs—the only known non-avian dinosaur embryos from Gondwana—are described from a nesting ground in the Upper Cretaceous stage of Patagonia, Argentina and it is proposed that these specimens belong to the same sauroPod species.
Early juvenile pterosaurs (Pterodactyloidea: Pterodaustro guinazui) from the Lower Cretaceous of central Argentina
We report on two juvenile specimens of Pterodaustro guinazui , a medium-sized, filter-feeding pterodactyloid pterosaur from the Lower Cretaceous (Albian) lacustrine deposits of the Lagarcito
Comments on Triassic pterosaurs with discussion about ontogeny and description of new taxa.
TLDR
The present study increases the diversity of Triassic flying reptiles and further pushes the origins of this clade back to at least the Middle Triassic.
Histovariability in bones of two pterodactyloid pterosaurs from the Santana Formation, Araripe Basin, Brazil: preliminary results

TLDR
Results of the histological analysis of two pterodactyloid pterosaurs from the Romualdo and Crato Members of the Santana Formation show variations in different bones of the same individual represent differential growth rates.
Development of the dentition in Alligator mississippiensis. Later development in the lower jaws of embryos, hatchlings and young juveniles
TLDR
Development of the lower dentition from stage 19 (day 26) embryos to 11 days after hatching (day 76) was studied in a close series of accurately aged specimens of Alligator mississippiensis using macroscopy, light microscopy, scanning electron microscope, radiography and detailed reconstructions, providing the first careful documentation of dentition development in any non-mammalian tetrapod from the first initiated tooth to the first erupted and functional dentition.
