Temporal range: Upper Jurassic–Recent 
|Shovelnose guitarfish, Rhinobatos productus|
J. P. Müller & Henle, 1837
The guitarfish are a family, Rhinobatidae, of rays. The guitarfish are known for an elongated body with a flattened head and trunk and small ray like wings. The combined range of the various species is tropical, subtropical and temperate waters worldwide. They often travel in large schools.
Guitarfishes have a body form intermediate between those of sharks and rays. The tail has a typical shark-like form, but in many species, the head has a triangular, or guitar-like shape, rather than the disc-shape formed by fusion with the pectoral fins found in other rays.
Nelson's 2006 Fishes of the World recognized four genera in this family: Aptychotrema, Rhinobatos, Trygonorrhina, and Zapteryx; other taxa once placed in the Rhinobatidae, such as Platyrhinoidis and Rhina, have since been moved to their own families. Recently, the genus Glaucostegus has again become recognized as distinct from Rhinobatos. The status of Tarsistes is dubious.
