  abstract = {{A}mazonia contains one of the world's richest biotas, but origins of this diversity remain obscure. {O}nset of the {A}mazon {R}iver drainage at approximately 10.5 {M}a represented a major shift in {N}eotropical ecosystems, and proto-{A}mazonian biotas just prior to this pivotal episode are integral to understanding origins of {A}mazonian biodiversity, yet vertebrate fossil evidence is extraordinarily rare. {T}wo new species-rich bonebeds from late {M}iddle {M}iocene proto-{A}mazonian deposits of northeastern {P}eru document the same hyper-diverse assemblage of seven co-occurring crocodylian species. {B}esides the large-bodied {P}urussaurus and {M}ourasuchus, all other crocodylians are new taxa, including a stem caiman-{G}natusuchus pebasensis-bearing a massive shovel-shaped mandible, procumbent anterior and globular posterior teeth, and a mammal-like diastema. {T}his unusual species is an extreme exemplar of a radiation of small caimans with crushing dentitions recording peculiar feeding strategies correlated with a peak in proto-{A}mazonian molluscan diversity and abundance. {T}hese faunas evolved within dysoxic marshes and swamps of the long-lived {P}ebas {M}ega-{W}etland {S}ystem and declined with inception of the transcontinental {A}mazon drainage, favouring diversification of longirostrine crocodylians and more modern generalist-feeding caimans. {T}he rise and demise of distinctive, highly productive aquatic ecosystems substantially influenced evolution of {A}mazonian biodiversity hotspots of crocodylians and other organisms throughout the {N}eogene.},
