Analyzing the clusters

Let's see what more we can learn from the clusters.

First we can see that the dots cluster into well-known groups*.
Violet dots for Aves.
Dark blue for Dromaeosauridae.
Light blue for Troodontidae.
Red for Compsognathidae.
Pink for Tyrannosaurs.
Green (light and dark) for Oviraptors.

This gives credence to the placement of the dots.
But what is striking is that the clusters are separate from each other. There are no lines of intermediates.
And it is clear how Senter established the Birdlike cluster and the Tyrannosaur cluster. It is clear that they are separate.

*There are other groups than the ones I listed, but these are the ones of most interest.
