TL;DR: In the case of the Romualdo Member of the Santana Formation Konservat Lagerstatten of north-east Brazil, it was first dated as Cretaceous by Agassiz on the basis of fish fossils obtained by Bavarian explorers Spix and Martius between 1817 and 1820 as discussed by the authors.

TL;DR: In the interior of northeastern Brazil there occurs the Santana Formation of Aptian age, composed lithologically of three members: Crato - an alternation of thin limestones and shales; Ipubi - gypsum; and Romualdo - almost pure limestone as discussed by the authors.

TL;DR: The family Chongichthyidae shows some morphological similarities to elopiforms, pachyrhizodontoids, clupeomorphs, osteoglossomorphs and euteleosts, but it also differs from all of them in certain respects and is therefore regarded as Teleostei incertae sedis.
Abstract: The new family Chongichthyidae is based on Chongichthys dentatus n. gen. et sp. from the Oxfordian marine deposits of the Domeyko Range, southeast of Antofagasta, northern Chile. Chongichthys dentatus differs from other Late Jurassic teleosts of South America and Europe in having: fenestrae between the prootic, auto-sphenotic and pterotic, and between the basioccipital, exoccipital, prootic and parasphenoid; a prootic fenestra; a large basisphenoid; a small, elongate basioccipital; a distinctive lower jaw; wide supraneurals; epineurals fused to the neural arches; ribs on the first abdominal centra and a distinctive enlargement of the last pleural ribs. The family Chongichthyidae shows some morphological similarities to elopiforms, pachyrhizodontoids, clupeomorphs, osteoglossomorphs and euteleosts, but it also differs from all of them in certain respects and is therefore regarded as Teleostei incertae sedis.

TL;DR: A character assemblage clearly demonstrates the necessity of including stem taxa in phylogenetic analysis based on morphology to resolve the controversial relationships of these basal teleostean fishes.
