2023 - Research.com Earth Science in Brazil Leader Award
2013 - Fellow, The World Academy of Sciences
His scientific interests lie mostly in Paleontology, Cretaceous, Pterodactyloidea, Anatomy and Azhdarchidae. Within one scientific family, Alexander W.A. Kellner focuses on topics pertaining to Ecology under Paleontology, and may sometimes address concerns connected to Clade. His biological study spans a wide range of topics, including Gondwana and Tetrapod.
The concepts of his Pterodactyloidea study are interwoven with issues in Rhamphorhynchidae and Skeleton. His Anatomy research is multidisciplinary, incorporating elements of Taxon and Santa María Formation. His Azhdarchidae research incorporates elements of Tapejaridae, Zoology and Evolutionary biology.
Alexander W.A. Kellner spends much of his time researching Paleontology, Cretaceous, Pterodactyloidea, Anatomy and Tapejaridae. His research in Structural basin, Aptian, Azhdarchidae, Taxon and Santana Formation are components of Paleontology. His Cretaceous research includes themes of Zoology, Ecology and Gondwana.
Alexander W.A. Kellner combines subjects such as Jiufotang Formation, Yixian Formation and Rostrum with his study of Pterodactyloidea. His study focuses on the intersection of Anatomy and fields such as Bauru Group with connections in the field of Titanosaur. His Tapejaridae research is mostly focused on the topic Thalassodromeus.
Alexander W.A. Kellner mainly focuses on Cretaceous, Paleontology, Structural basin, Theropoda and Crato Formation. His Cretaceous study combines topics from a wide range of disciplines, such as Zoology, Sedimentary rock, Marl and Gondwana. When carried out as part of a general Paleontology research project, his work on Aptian, Pterodactyloidea and Bone bed is frequently linked to work in Crest, therefore connecting diverse disciplines of study.
His Pterodactyloidea research is multidisciplinary, relying on both Outcrop, Ridge and Paleoecology. His studies deal with areas such as First phalanx, Crocodyliformes, Sarcosuchus and Humerus as well as Structural basin. Alexander W.A. Kellner focuses mostly in the field of Theropoda, narrowing it down to topics relating to Coelurosauria and, in certain cases, Group, Stratigraphic unit and Tetrapod.
Alexander W.A. Kellner mainly investigates Cretaceous, Paleontology, Osteology, Evolutionary biology and Pterodactyloidea. His work deals with themes such as Taxon, Crocodyliformes, Structural basin and Sarcosuchus, which intersect with Cretaceous. The study of Paleontology is intertwined with the study of Coelurosauria in a number of ways.
The study incorporates disciplines such as Lognkosauria, Clade, Saltasauridae, Lithostrotia and Saltasaurinae in addition to Osteology. Alexander W.A. Kellner has researched Evolutionary biology in several fields, including Sister group, Skull, Thalassodromeus, Synapomorphy and Appendicular skeleton. His Pterodactyloidea study integrates concerns from other disciplines, such as Outcrop, Ridge, Paleoecology and Bone bed.
