Size: The specimen is 76 cm (31 1/2”) in length
Fossil Location: Romualdo Member of the Santana Formation, Late Aptian-Cenomanian
(108-92 million years ago). Ceara, Northeastern Brazil
an amazing and very rare bowfin fish specimen! This Calamopleurus specimen
was found in a concretion consisting of three parts that were carefully
reassembled. Overall the preservation is excellent. The head is neatly
complete with the jaw retaining many large teeth. The pelvic and anal
fins are partially intact. Dorsal fin missing. The caudal fin is excellent.
Large and thick rectangular scales are present the entire length of
the body. There is no carving or restoration on any parts of this Calamopleurus.
A fossil fish of this size, rarity and preservation would certainly
grace any collection, be it public or private! These were middle to
large freshwater fishes of elongate shape. Head elongate, snout somewhat
rounded, eyes small with long pointed teeth. Dorsal fin triangular,
caudal fin rounded. Large and thick triangular scales. Genus extinct.
Closely related to the recent bowfin, Amia calva. (See page 433 of
Frickhinger’s book FOSSIL FISH ATLAS for more detailed information.)
Bowfins are an order (Amiiformes) of primitive ray-finned fish. Only
one species, the bowfin Amia calva, family Amiidae, exists today, although
additional species in six families are known from Jurassic, Cretaceous,
and Eocene fossils. These included the huge Leedsichthys, probably
the biggest fish that ever existed. The bowfin and the gar are two
of the freshwater fishes still extant that existed, almost unchanged
from their current form, while the great dinosaurs roamed the earth.
Brazil a few years ago banned the export of fossils from the Santana
Formation. This fish was purchased from the estate liquidation of a
deceased fossil dealer and is perfectly legal. This is a unique opportunity
to obtain a premium grade fossil fish from a site now closed to commercial
