Belantsea (named after a legendary ancestor of the Crow Nation) is a genus of extinct petalodontid cartilaginous fish that lived during the Lower Carboniferous, about 350 million years ago. Its fossils are found in the Bear Gulch Limestone lagerstätte. Its body was leaf-shaped, with muscular fins and a small tail. Such a body plan would allow for great maneuverability, but at the cost of speedy cruising. Its few, large, triangular teeth formed a beak-like arrangement that allowed it to graze bryozoans, sponges, crinoids, and other encrusting animals. The genus contains two species, B. montana and B. occidentalis.

| - Belantsea es un género extinto de holocéfalo del orden Petalodontiformes, que surgió en el Periodo Carbonífero, y desapareció en la extinción masiva del Pérmico-Triásico. Se caracterizaba por tener una forma singular, ya que parecía un pez óseo en vez de un pez cartilaginoso; de hecho, está lejanamente emparentado con las actuales quimeras. Se alimentaba de esponjas ancestrales, braquiópodos, crinoideos, crustáceos y peces pequeños. Belantsea montana es la representación clásica de orden Petalodontiformes. (es)
- Il Belantsea montana Lesueur, 1818 (nome che deriva da un'antica leggenda della tribù di Nativi Americani Crow) era un pesce cartilagineo dall'aspetto peculiare che è vissuto durante il Carbonifero inferiore. I fossili di questo animale sono stati ritrovati nella lagerstätte nel Montana. La specie è l'unica del genere Belantsea e la più conosciuta dell'ordine Petalodontiformes. (it)
- Belantsea é um gênero de peixes cartilaginosos petalodontídeos extintos que viveram durante o Carbonífero Inferior. Seu corpo era em forma de folha, com nadadeiras musculosas e uma pequena cauda. Tal forma de corpo permitiria grande manobrabilidade, mas ao custo de um cruzeiro veloz. Seus poucos dentes grandes e triangulares formavam um arranjo em forma de bico que lhe permitia pastar briozoários, esponjas, crinóides e outros animais incrustantes. Belantsea é o membro mais conhecido da ordem Petalodontiformes. (pt)
- Το Belantsea είναι ένα γένος των εξαφανισμένων petalodontid cartilaginous ψαριών και έζησε κατά τη διάρκεια της Κάτω λιθανθρακοφόρου, περίπου πριν από 350 εκατομμύρια χρόνια. Τα απολιθώματα του βρέθηκαν στο Bear Gulch Limestone lagerstätte. Το σώμα του είχε σχήμα φύλλου, με μυϊκά πτερύγια και μια μικρή ουρά. Ένας τέτοιος σωματότυπος θα του επέτρεπε μεγάλη ευελιξία, αλλά με το κόστος της ταχείας πλεύσης. Είχε λίγα, μεγάλα και τριγωνικά δόντια που σχημάτιζαν μια διάταξη ράμφους που του επέτρεπε να βόσκη βρυόζωα, σπόγγους, crinoids, και άλλων εξωσκελετικα ζώα. Το γένος περιλάμβανε δύο είδη, το B. montana και το B. occidentalis. (el)
