Description

The situation of bony fishes after the end of the Cenozoic (149 million years after humanity) became quite precarious, with the loss of much of its diversity caused by anoxic events and the collapse of food chains in large rivers, Lakes, seas and oceans. Throughout the terrestrial hydrosphere, the survivors barely managed to diversify in a way that by the middle of the Therozoic era they developed the same level, adopting totally different forms, with different niches and new and varied adaptations.

In the warm open oceans of the period Metamonus (266-349 million years) the warm and nutritious waters laid the foundations to support new varieties of filter feeders, especially the huge forms, and in this time fishes get the way to fill this niche with a dozens of species, but one in particular stands out among the majority by a rather aberrant mouth. The baleen Cheek-fan (Baleenebuccia magnificus) is a giant representative of a group of strange bony fishes characterized by their erect posture, development of the pectoral and pelvic fins for swimming and almost atrophies the caudal, being in benthonic species developed as a prehensile appendices or a weapon.

The cheek-fan, however, unlike any of its relatives, has the ability to deploy the maxillary and extend 2 huge membranes which are capable of catching the plankton and small fishes. It’s about 18 to 20 meters long, with a maxillary width of around 13 to 15 m; this species is a peaceful being, which swim between currents in the open oceans at depths of between 50 and 100 meters deep. To mobilize it uses both its small but muscular fins as its still developed caudal tail, and in some cases it can use the individual maxillary to gain speed and control. Its head is quite enormous, being 1/3 of the total length, being largely covered with hard bone plates, of which only have 2 small eyes that are located in front; The body is bulky and robust, with 2 pairs of fins, the pectorals being quite developed and the pelvic fins greatly reduced; The tail is huge, elongated and has the function as much as a keel as a limb to mobilize. The longevity of this species can be quite long by its slow metabolism, coming to live some individuals up to 150 years.
