Estimating Divergence Times in Large Phylogenetic Trees | Systematic Biology | Oxford Academic
If a specific node is of interest to you, you will need to go to the scientific literature which will give you much more information about what we know and what we roughly guess. Open Tree of Life could be what you're after.
It was updated last month according to this page. The visual interface is rather bland, but that's probably the price one has to pay for accuracy and completeness. Vertebrates, arthropods and molluscs are all available as categories in the taxon search bar on the home page.

BEAST performed the best of all methods when running 10 6 steps, but this also took the most time. In contrast, BEAST performed poorly when limited to 10 4 steps, requiring roughly the same amount of computing time as node.
Furthermore, results using BEAST are not strictly comparable, since we used sequence data as inputs instead of the phylogenetic trees. The runtime and the accuracy of node. In this section, we provide a visualization of sequence data using the estimated dates of internal nodes.
We estimated the dates of the internal nodes using node. In Figure 1 , we show the genetic distance from the root versus time of the internal nodes and sampled sequences. The dates of the internal nodes were estimated using node.

The edges between adjacent nodes of the tree are drawn as solid lines and the molecular clock is drawn by a dashed line. One drawback of our methodology is that it assumes that the phylogeny follows a strict molecular clock. However, the local likelihood model can be extended to incorporate a variable molecular clock; future work would like to include this extension.
The molecular clock assumption implies that mutations are strictly additive over time, which is not true. National Center for Biotechnology Information , U. Published online Nov Jones 1, 2 and Art F. Poon 2, 3, 4.
