A review of all Mesozoic synapsids of South America, as well as surviving Cenozoic lineages of those groups. Apparently done in quarentine.
I strongly recommend this book. It's not wholly accessible to those not in palaeotological lingo, but it has some cute wit sometimes.
Bombshells:
- Brasilestes might not be a mammal, but a notosuchian tooth. So far all supposed therians from the Cretaceous of South America seem to be meridiolestidans, so hurray for dryolestloids.
- It interprets volaticotheres as gliding piscivores. Seems honestly easier to admit they were flyers, but cool nonetheless.
- While Groeberia is indeed a metatherian, the jury is still out on Patagonia, which doesn't seem to have anything diagnosing it as a therian (granted, the gondwanathere interpretation is still treated cautiously).
Just read this thing already.
