Updated June 23, 2017 with the replacement of the cladogram with one containing more recently added taxa.
After earlier identifying
phylogenetic miniaturization at the bases of several major clades in the large reptile tree (LRT, 969 taxa), I wondered if similar size-related patterns appear in basal tetrapods.
- Osteolepis is smaller than Eusthenopteron. Has anyone removed the scales from the fore fins of Osteolepis to see what the bones inside look like?
- Ventastaga and Pederpes are successively smaller than Ichthyostega.
- Koilops is much smaller than Panderichthys..
- Eucritta is much smaller than Proterogyrinus, both in overall size and in relative torso length. Eucritta nests at the base of the Seymouriamorpha + Crown Tetrapoda.
