[1] Denise Sigogneau-Russell completed her PhD in 1969 on therapsids - the forerunners of mammals - from South Africa, where she spent two years.
Zofia Kielan-Jaworowska said that due to Sigogneau-Russell's "scholarship and diligence, she has contributed enormously to the knowledge of early mammal evolution.".
She has also written reviews of the anatomy and taxonomy of synapsids[3] and therapsids, as well as co-authoring papers on more recent fossil mammals.
In 1991 she published a book on Mesozoic mammals, Les mammifères au temps des dinosaures [7] She has authored over 56 research papers and contributed many more articles on palaeontology.
She has named at least 3 orders and families, 5 genera, and 5 species of Mesozoic mammal from the Triassic, Jurassic and Cretaceous periods.
