Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Baltic amber and other fossil resins in the light of physicochemical studies
The paper presents some problems in the studies on Baltic amber (succinite) and other fossil resins. Natural resins form a large group of fossils already known from various parts of the world. However, they markedly differ in age and origin which creates

The Geological-Evolutional Concept of Resin Genesis
Geological and evolutionary concept of the genesis of fossil resins: Fossil resins are a special group of natural organic compounds. The work is devoted to the determination of special features of formation, distribution, properties, composition of ...

Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

Characterisation and Classification of fossil resins
Since the sixties there have been numerous works dealing with the classification of different types of amber based on spectroscopical data. Most of them were restricted to a visual inspection of the fingerprints or simple spectral comparisons.
