I gave the specific prediction, based on evolutionary principles and the state of the fossil record, and 20 years in the waiting for confirmation, of the transitional form named Diarthrognathus.
Funny you should mention that.
Diarthrognathus lacks the dental specialization of the tritylodonts; thus, its transitional status can be questioned.
The skeletal remains of many "transitional" forms, such as Diarthrognathus, are fragmentary. Furthermore, the demarcation between the reptilian [92] and mammalian structures is becoming blurred as knowledge about each group increases. The diagnostic characteristics of the class Mammalia essentially reside in the soft anatomy and physiology that cannot be determined from skeletal remains. Therefore, the classification of mammalian fossil according to skeletal features is tentative. In addition, the almost simultaneous appearance of Diarthrognathus (late Triassic era) and the first known mammal fossil (Triassic-Jurassic boundary) leaves little time for the evolution of mammals from this presumed transitional form.
http://www.ibri.org/Books/Pun_Evolution/Chapter2/2.2.htmThe existence of just one confirmed prediction is sufficient to confirm the general principle. How many more individual examples do you need?
I and any person with more than two brian cells to rub together need an example that can't be shot down in less than five minutes and one internet search.
