On June 9, the journal Current Biology published for the first time an almost complete extinction of an extinct giant dolphin species found in what is now South Carolina. This 15-foot-long dolphin (Ankylorhiza tiedemani comb. N.) Roamed the earth about 25 million or two and a half billion years ago during the Oligocene period, the existence of which has so far been found only in fossils called partial rostrum (snot).

According to researchers, the structure of the skull, teeth, flipper and spine proves that this giant dolphin was the best hunter of its time. The species has evolved in parallel, as these whale species thrive in the same aquatic climate as these dolphins. Some of the characteristics of the current Balinese whale or toothed whale have come from this dolphin species through parallel evolution, as these whale species grow in the same aquatic climate as these dolphins.

Robert Bosenecker of Charleston College, South Carolina, said: "It's amazing that the way the balloon whale and the dolphin have mastered the same swimming technique has evolved from their different ancestors. There are other examples, such as a narrowing of the tail structure, an increase in the number of vertebrae in the tail, and a shrinkage of the humerus.
