with the shifting of taxa based on new skull identities, plus the addition of several more closely related taxa. See the large reptile tree for the latest updates, not always repaired here.
In the large reptile tree (LRT, 1569 taxa) Late Carboniferous Coccocephalichthys among the paleoniscids. Several bones are re-identified above based on tetrapod homologs.
Most of the time,
this is how the LRT grows, by adding new transitional taxon between two presently tested taxa. In this case, the transitional taxon neatly helps illustrate the evolution that occurred between the two extremes. Using tetrapod labels (Fig. 2) has proven to help us understand the identity of facial bones in these fish.
Using colors to identify bones
is something I started doing in the vampire pterosaur, Jeholopterus (see header above, far right) in 2003. I was wondering if someone could send me an earlier example of this graphic technique? Today it seems to be growing in popularity, especially so since there are no additional color charges for papers published online.
