GoKawiilFossil study of Jurassic swimmer Megacauda reveals early mammal throat evolution
Researchers analyzing the Jurassic mammaliaform Megacauda identified a derived, therian-like pterygoid hamulus structure in its skull, contrasting with the more primitive configuration seen in Morganucodon. Comparisons with the modern marsupial Didelphis virginiana, including diceCT scans, show how this bony hook relates to muscles controlling the soft palate and pharynx.
