Self-portrait, 1912. Gerhard Heilmann (later sometimes spelt "Heilman" [1]) (25 June 1859 – 26 March 1946) was a Danish artist and paleontologist who created artistic depictions of Archaeopteryx, Proavis and other early bird relatives apart from writing the 1926 book The Origin of Birds, [2] a pioneering and influential account of bird evolution.
Gerhard Heilmann's hypothesized bird ancestor "Proavis" (1916) Some authors have remarked on a darker, more sinister feel to his paleoart than that of his contemporaries, speculating that this style was informed by Burian's experience producing artwork in his native Czechoslovakia during World War II and, afterwards, under Soviet control.
In the 1920s, studies by the celebrated palaeontologists Alfred Romer and Gerhard Heilmann (Heilmann, 1926) had confirmed that dinosaurs had broad avian-like hips rather than those of a typical reptile. Knight often restored extinct mammals, birds and marine reptiles in very dynamic action poses, but his depictions of large dinosaurs as ...

[4] [5] However, in 1926, Gerhard Heilmann wrote his influential book The Origin of Birds, [6] in which he dismissed the dinosaur–bird link, based on the dinosaurs' supposed lack of a furcula. [7] Thereafter, the accepted hypothesis was that birds evolved from crocodylomorph and thecodont ancestors, rather than from dinosaurs. This removed ...
In the following years, as of 1913, Danish artist and amateur zoologist Gerhard Heilmann also used and popularised the term Proavis, this time presenting the public with more accurate and anatomically probable drawings. Heilmann favoured a scientific model in which the assumed Proavis was arboreal and of thecodontian descent, thus not a dinosaur.

The Origin of Birds is an early synopsis of bird evolution written in 1926 by Gerhard Heilmann, a Danish artist and amateur zoologist.The book was born from a series of articles published between 1913 and 1916 in Danish, and although republished as a book it received mainly criticism from established scientists and got little attention within Denmark.
