al. (2007) found it to be a plateosaurid, supporting Bonaparte's placement. However, the analyses of Benton et al. (2000) and Yates (2003) recovered it in a polytomy with other basal sauropodomorphs or as a massospondylid, respectively. Subsequent analyses such as Yates et al. (2010), Apaldetti et al. (2013; 2014), Wang et al. (2017), and Müller (2020) have reached the consensus that Coloradisaurus is a massospondylid most closely related to Lufengosaurus and Glacialisaurus. These three taxa share four synapomorphies found in the metatarsals and femur. Below is a simplified cladogram after Galton & Upchurch (2004), reflecting its early placement as a plateosaurid. Below is a simplified cladogram after Müller (2020), showing its current position as a massospondylid.
