Does morphology reflect osteohistology-based ontogeny? A case study of Late Cretaceous pterosaur jaw symphyses from Hungary reveals hidden taxonomic diversity

Abstract With a single complete mandible and 56 mandibular symphyseal fragments of various sizes, the Late Cretaceous Hungarian azhdarchid material has been considered one of the most extensive monospecific pterosaur assemblages in the world. Representing a broad size range, these elements have been thought to demonstrate a developmental series of Bakonydraco galaczi. As such, they were ideal to test whether absolute size and/or morphology reliably indicate relative ontogenetic stages in this…

The fossil record of Mesozoic tetrapods in Bulgaria is sparse and currently limited to the Maastrichtian limestones of the Kajlâka Formation. Herein we report on two bone fragments from the Upper…
Comparative bone histology of rhabdodontid dinosaurs

Qualitative comparison of bone histology of corresponding ontogenetic stages and elements among the three valid rhabdodontid genera, Mochlodon, Zalmoxes, and Rhabdodon, revealed some consistent patterns, which indicate a prolonged phase of fast growth and a less constrained cyclicity in the growth dynamics of R Habdodon.

It is concluded that in the Anhangueria clade, the growth of bones is not compatible with the ontogenetic stage, and young animals may present large proportions, whereas there were older individuals of smaller sizes in the same clade.
COMMENTS ON TRIASSIC PTEROSAURS WITH A COMMENTARY ON THE "ONTOGENETIC STAGES" OF KELLNER (2015) AND THE VALIDITY OF BERGAMODACTYLUS WILDI

Six stages (OS1-6) were identified by Kellner (2015) to establish the ontogeny of a given pterosaur fossil and were used to support the erection of several new Triassic taxa including Bergamodactylus wildi, which is here retained within the taxon Carniadactylu rosenfeldi as proposed by Dalla Vecchia (2009a).

Fossil forms often display developmental traits absent or rare among modern ones such as polydactyly, hyperphalangy, the presence of ribcage armour, reduction of head ornamentation during ontogeny, extreme modifications of vertebral count or a wide range of feather-like structures, which provide an empirical background for many morphogenetic considerations.

It is shown that there is no clear evidence that dinosaurs or other groups were undergoing long-term declines in Europe prior to the bolide impact, and the importance of the European record in understanding the end-Cretaceous extinction is discussed.

The presence of fibrolamellar bone, which is accompanied with increased growth rates and presumably even with increased metabolic rates, already in Anarosaurus and Cymatosaurus can explain the success of the Pistosauroidea, the only sauropterygian group to survive into the Jurassic and give rise to the pelagic plesiosaur radiation.

It is hypothesize that sexual maturity was attained at HOS-8, well before maximum size was attained, but it did not find sexually differentiated growth trajectories subsequent to HOS -8, and Histologic ontogenetic stages generally correlate closely with body size and thus provide a means to resolve important issue like the ontogenetics status of questionable specimens.
