Sclerorhynchids (extinct sawfishes, Batoidea), pristids (extant sawfish, Batoidea) and pristiophorids (sawsharks, Squalomorphi) are the three elasmobranch families that possess an elongated rostrum with lateral teeth. Sclerorhynchids are the extinct sawfishes of the Cretaceous period, which reached maximum total lengths of 100 cm. The morphology of their rostral teeth is highly variable. Pristid sawfish occur circumtropically and can reach maximum total lengths of around 700 cm. All pristid… 
Paleobiology of the Late Cretaceous sclerorhynchid sawfish, Ischyrhiza mira (Elasmobranchii: Rajiformes), from North America based on new anatomical data
Abstract We describe seven associated skeletal remains of Ischyrhiza mira, a Late Cretaceous sclerorhynchid sawfish, from the Campanian‒lower Maastrichtian of Tennessee and Alabama, U.S.A., to
Sclerorhynchus atavus and the convergent evolution of rostrum-bearing chondrichthyans
TLDR
For the first time a fossil rostrum could be compared with living forms and Smith Woodward suggested that Sclerorhynchus be assigned to the Pristidae, although acknowledging that the rostra are very different.
A rhinopristiform sawfish (genus Pristis) from the middle Eocene (Lutetian) of southern Peru and its regional implications
Modern sawfishes (Rhinopristiformes: Pristidae) are circumglobally distributed in warm waters and are common in proximal marine and even freshwater habitats. The fossil record of modern pristid
Evolutionary origins and development of saw-teeth on the sawfish and sawshark rostrum (Elasmobranchii; Chondrichthyes)
TLDR
It is suggested that saw-teeth in Pristiophoridae and Sclerorhynchoidea represent modified dermal denticles and lack the ‘many-for-one’ replacement characteristic of elasmobranch oral dentitions.
The first three-dimensional fossils of Cretaceous sclerorhynchid sawfish: Asflapristis cristadentis gen. et sp. nov., and implications for the phylogenetic relations of the Sclerorhynchoidei (Chondrichthyes)
TLDR
A phylogenetic analysis using both parsimony and Bayesian methods recovered a phylogenetic topology that places the sclerorhynchoids in a close relation to rajoids and clearly separated from the morphologically similar Pristidae within the Rhinopristiformes.
The Long-Rostrumed Elasmobranch Bandringa Zangerl, 1969, and Taphonomy Within a Carboniferous Shark Nursery
TLDR
A new reconstruction of Bandringa incorporates several previously unreported features, including ventrally directed jaws, stellate squamation, a branched lateral line, and fin spines bearing smooth costae, which provide a more complete picture of hard- and soft-tissue anatomy than resident taxa from a single deposit.
Sawfishes and Other Elasmobranch Assemblages from the Mio-Pliocene of the South Caribbean (Urumaco Sequence, Northwestern Venezuela)
TLDR
It is hypothesize that the fossil chondrichthyan assemblages from the Urumaco sequence are evidence for marine shallow waters and estuarine habitats, using the habitat preference of the living representatives.

The systematic position of the Cretaceous sclerorhynchid sawfishes (Elasmobranchii, Pristiorajea)
TLDR
A hypertrophied roStral cartilage with lateral rostral spines was developed independently within several closely related clades according to the present hypotheses, and a new order, †Sclerorhynchiformes, is introduced.
New data on the systematics and interrelationships of sawfishes (Elasmobranchii, Batoidea, Pristiformes)
TLDR
This investigation of the dermal covering provides results which agree with studies that separate the same two species groups of Pristis on the basis of other morphological data.

TLDR
Observations on reproductive staging and the capture of neonate specimens suggest that in all four pristids, pupping occurred through the wet season until the beginning of the dry season in May, and a seasonal set net closure for the barramundi, Lates calcarifer and shark fisheries, therefore offers a measure of protection to breeding female sawfish and their offspring.

Threatened fishes of the world: Pristis pectinata Latham, 1794 (Pristidae)
TLDR
In US waters there was evidence for a seasonal migration of adults along the east coast from winter grounds in eastern Florida to summer grounds in Georgia, South Carolina, North Carolina, Virginia, and at times as far north as NewYork.
Freshwater Sawfish Pristis microdon Latham, 1794 (Chondrichthyes : Pristidae) in the Kimberley region of Western Australia
TLDR
Observations of sexual maturity, annuli present on vertebrae, recaptures of tagged individuals and length-frequency data suggested that the freshwaters of the Fitzroy River are a nursery for this species where immature individuals remain for a maximum of four or five years.

TLDR
Increase in assemblage diversity throughout the Jurassic and Cretaceous suggests that radiation events resulted in real and dramatic increases in diversity, and that the perceived diversification is not an artifact of poor knowledge.
First record of the freshwater sawfish, Pristis microdon, from southwestern Australian waters
Sawfishes (family Pristidae) are large (up to 7m) modified batoids with a blade-like snout edged with pairs of rostra I teeth. They occur worldwide in sub-tropical and tropical shallow coastal sea,
