I love the specificity of the 9 million figure, 1.5 billion years ago.
You set me off on some reading to find out more as it seems so interesting, but I can't find a detailed figure, so I like exactness your estimate provides.
Amazing to consider what the common ancestor was like and also what our animal ancestors were like at that time.
This paper by Taylor & Berbee [1] describes one attempt at dating the divergence of clades on the evolutionary tree. Figure 2 shows the evolutionary tree inferred from analyzing the similarity of gene sequences between species. Table 1 shows estimates of the age of last common ancestors.
