One of the properties of fossils is to provide unique ontogenies that have the potential to
inform us of developmental patterns and processes in the past. Although fossilized …

ABSTRACT Extinct lamniform sharks (Elasmobranchii: Lamniformes) are well represented in
the late Mesozoic‒Cenozoic fossil record, yet their biology is poorly understood because …

Different interpretations on the timing of early diversification and radiation of modern sharks
and batoids (Neoselachii) in the Earth's history exist and are related to discrepancies in …

The Late Jurassic-Early Cretaceous (164–100 Ma) represents one of the main transitional
periods in life history. Recent studies unveiled a complex scenario in which abiotic and …

Deep-sea Lantern Sharks (Etmopteridae) represent the most speciose family within Dogfish
Sharks (Squaliformes). We compiled an extensive DNA dataset to estimate the first …

During their evolutionary history, modern sharks developed different tooth mineralization
patterns that resulted in very distinct histological patterns of the tooth crown (histotypes). To …

Sharks are among the oldest vertebrate lineages in which their success has been attributed
to their diversity in body shape and locomotor design. In this study, we investigated the …

The cartilaginous fishes (Chondrichthyes) have a rich fossil record which consists mostly of
isolated teeth and, therefore, phylogenetic relationships of extinct taxa are mainly resolved …

(Chondrichthyes, Neoselachii).—Zoologica Scripta, 39, 37–49. Identifying the monophyly …

The fossil record of chondrichthyans (sharks, rays and chimaeroids) principally consists of
isolated teeth, spines and dermal denticles, their cartilaginous skeleton being rarely …
