Maurice Jules Marie Collignon (9 June 1893, Saint-Malo – 21 October 1978, Moirans) was a French geologist and paleontologist, who is best known for his research of Cretaceous period ammonites from Madagascar.
In the meantime he conducted geological and paleontological research; as early as 1928 he was providing descriptions of ammonite fauna from Madagascar.
[1] In 1950 he retired from military service with the rank of major general.
He then joined the Service géologique d'outre-mer as a paleontologist,[2][3] and afterwards directed four 6-month missions of paleontological exploration in Madagascar (1952, 1953, 1954, 1957).
[3] During his career, he described numerous fossil taxa, such as the ammonite genus Cunningtoniceras.
