Alexander Wilhelm Armin Kellner (born September 26, 1961) is a Brazilian

Period, including extinct dinosaurs and crocodylomorphs.[1]

Kellner has over 500 publications to his name, has published more than 160 primary studies and two science books. He has participated in paleontological expeditions to many locations including Brazil, Chile, Iran, the United States, Argentina, China, and Antarctica.

His scientific achievements include the description of more than thirty

TWAS Prize for Earth Sciences from The World Academy of Sciences and admission to the National Order of Scientific Merit
(class Comendador), one Brazil's most prestigious awards.

Biography

Kellner was born in Vaduz, Liechtenstein, son of a German father and Austrian mother.[2] In his early childhood he moved with his parents to Brazil, where he became naturalised Brazilian.[1]

In

Anais da Academia Brasileira de Ciências, the official publication of the Brazilian Academy of Sciences.[3]

As part of his work on flying reptiles, Kellner organised the Pterosaur Workshop at Pittsburgh, USA, in 1995,[4] and the first pterosaur symposium ever held at the American Museum of Natural History in 1996. As well, he was involved in the organisation of several scientific meetings in Rio de Janeiro such as the 31st International Geological Congress in 2000 and the 2nd Latin-American Congress of Vertebrate Paleontology in 2002.[1]

Kellner has organized or taken part in several paleontological expeditions to many locations around the globe, including Brazil—

Atacama, Chile and Kerman, Iran; Montana in the United States; Patagonia in Argentina;[1] the famous deposits of Liaoning, China,[5][6] and James Ross Island in Antarctica.[7][8]

Kellner has over 500 publications to his name (including abstracts and science articles). He has published more than 160 primary studies[4] and two science books: Pterossauros - os senhores do céu do Brasil ("Pterosaurs — Lords of the Brazilian Sky")[9] and the novel Na terra dos titãs ("In the Land of the Titans").[10] He has also taken part in documentaries about fossils (e.g., Antarctica - a Summer of 70 million Years and Dinosaur Hunters).[citation needed]

As a result of his scientific activity he has received several honours, being appointed a member of the Brazilian Academy of Sciences in 1997. He is also an honourable member of the New York Paleontologial Society and the Paleontological Society of Chile. He is a research associate of the American Museum of Natural History[1] and of the Chinese Institute of Vertebrate Paleontology and Paleoanthropology.[citation needed]

Besides his teaching activity, having advised over fifteen master and Ph.D. students, Kellner has been active in the propagation of scientific knowledge to the general public. He organised the 1999 exposition No Tempo dos Dinossauros ("In the Time of the Dinosaurs") at the

Brazilian Society for Scientific Progress.[12]

Apart from studying their fossils, Kellner has performed important theoretical work on pterosaurs, including

phylogeny. In this he is the founder of a distinctive Brazilian school of the study of pterosaurs, with its own favoured phylogenetic model, clade terminology and nomenclature. Rival models and nomenclatural choices have been devised by the influential British pterosaur researcher David Unwin.[citation needed
]

Kellner has received numerous honours and prizes, including the

TWAS Prize for Earth Sciences from The World Academy of Sciences.[13] He was admitted in the National Order of Scientific Merit
(class Comendador), one the Brazilian Federal Government's most prestigious awards.

List of species named by Kellner

Kellner's scientific achievements include the description of more than thirty species, of which Santanaraptor placidus (1996, 1999) is among the best examples of soft tissue preservation, including blood vessels and muscle fibers, reported in any dinosaur. The pterosaur Thalassodromeus sethi, which Kellner described in 2002 with his colleague Diogenes de Almeida Campos, allowed for the establishment of a new hypothesis regarding the use of the head crest in body temperature regulation of pterosaurs.[1]
