On Sacabambaspisjanvieri and the vertebrate diversity in Ordovician seas
Résumé
In this short review of Ordovician vertebrates, the authors summarize preliminary data on Sacabambaspis from the Ordovician of Bolivia (age, taphonomy, morphology). This is the base for comparisons with the Ordovician vertebrates of North America and Australia. Finally, the palaeogeographical problem of this distribution is settled.
