    Quaternary fossil shark (Neoselachii: Galeomorphii and Squalomorphii) diversity from southern Brazil
    Sharks are cartilaginous fish that appeared 245 million years ago and became a highly diversified group, occupying several niches successfully. On the coast of Rio Grande do Sul, Brazil, shark fossils are commonly found ex situ associated with accumulations

    Node age estimations and the origin of angel sharks, Squatiniformes (Neoselachii, Squalomorphii)
    The fossil record of angel sharks is reviewed with special focus on skeletal remains. A new family †Pseudorhinidae is established for two species based on complete specimens from the Late Jurassic and a possible third species based on isolated teeth.

    Shark fossil diversity (Squalomorphii, Squatinomorphii, and Galeomorphii) from the Langhian of Brielas (Lower Tagus Basin, Portugal)
    The fossiliferous marine Miocene sediments of the Lower Tagus Basin (Portugal) present a great diversity of Chondrichthyes forms. The current study focuses on the fossil sharks from the Langhian Vc unit of the Brielas section, located in the Setúbal Peninsula.

    Squalomorphii - Wikipedia

    Squalomorphii is a superorder of cartilaginous fishes, generally characterized by lacking traits such as an anal fin, nictitating membrane, or suborbital shelves in the cranium. Squalomorphii sharks are also called squalea, or squalean sharks. There are about 163 living species in 11 families. Squalean sharks are … See more

Squalean sharks are divided into four orders: the Hexanchiformes, Squaliformes, Squatiniformes, and Pristiophoriformes . The order Hexanchiformes is a very small and primitive order consisting of cow sharks and frilled sharks.

    When did Squalomorphii originate?
    Here, we assumed the origin of Squalomorphii, i.e. our root age, to have occurred between 190 and 279 Ma based on distinct Hexanchoid teeth from the Lower Jurassic as minimum age and the fossil appearance of Protracodus, the oldest tooth fossils that carry morphological characters of euselachians as a soft upper bound.

    What is a squaliform shark?
    The order Squaliformes is a large, ancient order of sharks. Sharks from this order have two dorsal fins -usually with spines-, no anal fin, and no nictitating membrane on the eyes. Squaliform sharks are extremely variable in size and shape, and can be found in most marine habitats throughout the world.
