English: Coelurosaur phylogeny showing the ‘dinosaur-bird’ transition between the Lower Jurassic and the present. Grey bars represent the period of existence of the different clades, based on its first and last appearance. Coloured symbols show macroevolutionary events related to each lineage (legend at the top right shows the meaning of each symbol). Flight capacity is based on Pei et al. (2020) and Dececchi et al. (2020). Evolutionary radiations are based on Benson et al. (2014) and Puttick et al. (2014). Forelimb, hindlimb and hand evolutionary dynamics are based on Benson and Choiniere (2013), Dececchi and Larsson (2013) and Nebreda et al. (2020). Finally, neurocranial expansion episodes are based on Walsh et al. (2016), Fabbri et al. (2017), Balanoff et al. (2018) and Beyrand et al. (2019). The dashed line marks the K-Pg boundary. Silhouettes are not to the same scale but try to represent the trend toward miniaturization along the Mesozoic.
