Overview

What is he best known for?

The fields of study he is best known for:

  • Paleontology
  • Genus
  • Ecology

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.

His most cited work include:

  • Pterosaur phylogeny and comments on the evolutionary history of the group (178 citations)
  • Pterosaur diversity and faunal turnover in Cretaceous terrestrial ecosystems in China (136 citations)
  • A NEW SAUROPOD DINOSAUR (TITANOSAURIA) FROM THE LATE CRETACEOUS OF BRAZIL (99 citations)

What are the main themes of his work throughout his whole career to date?

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.

He most often published in these fields:

  • Paleontology (49.40%)
  • Cretaceous (42.86%)
  • Pterodactyloidea (21.43%)

What were the highlights of his more recent work (between 2017-2021)?

  • Cretaceous (42.86%)
  • Paleontology (49.40%)
  • Structural basin (7.14%)

In recent papers he was focusing on the following fields of study:

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.

Between 2017 and 2021, his most popular works were:

  • Lack of science support fails Brazil (14 citations)
  • Brazilian legislation on genetic heritage harms Biodiversity Convention goals and threatens basic biology research and education. (13 citations)
  • A new toothless pterosaur (Pterodactyloidea) from Southern Brazil with insights into the paleoecology of a Cretaceous desert (12 citations)

In his most recent research, the most cited papers focused on:

  • Genus
  • Paleontology
  • Ecology

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.
