Phylogenetic relationships near the origin of extant crocodylians are weakly supported, and
this lack of resolution makes for poor estimates of taxonomic and morphological diversity …

Gars (Lepisosteidae) are ray-finned fishes with controversial relationships to other
actinopterygian lineages. When fossil taxa are considered, gars are grouped with Mesozoic …

The Jurassic is an important period for understanding the origin of modern fish faunas, since
it saw the first radiation-and in some cases the origin-of most modern groups. In …

The osteology of Thaiichthys buddhabutrensis, nov. gen., from the Late Jurassic–Early
Cretaceous of Thailand is described on the basis of a collection of well‐preserved …

A new genus and species of coelacanth, Parnaibaia maranhaoensis gen. et sp. nov. is

Archosaur osteological remains are abundant in Brazil, particularly from the Triassic and
Cretaceous strata, but in Jurassic, the record is predominantly represented by ichnofossils …

The early history of the Semionotiformes is still scarcely known as, apart from the Permian

Abstract Fossil bonanzas called Konservat Lagerstätten provide geological windows to the
ecology of ancient life communities. These deposits often occur as cluster of fossil localities …

ABSTRACT A revision of the semionotids from the Lower Cretaceous Lagarcito Formation of
Argentina leads to the conclusion that only one taxon, Neosemionotus puntanus Bocchino …

The lateral and vertical distribution of sedimentary facies and ichnofacies in lacustrine
systems records sensitive climatic variations and rates of subsidence. The Upper Jurassic …
