Fossils of Romundina Fish discovered by Scientist can throw light on the origin of Human Face

Creature without a face? There is no point of being selfish and assuming that just like human other creatures also had face, which was shaped and structured over the course of time. Well, for those who tend to disagree and feel that every creature was evolved with the head; latest scientific discovery defiantly appears to be at loggerheads with your assumption.

Earliest creature was found to be jawless with backbone. Romundina, an armored fish that swam the water for almost 415 million years, fossils of whose are unraveling the mysteries at Canadian Arctic. This is something amazing.

Romundina Fish, is being meticulously studied by French and Swedish scientist and everything is articulated. According to expert, fossil of Romundina fish can help to solve the mystery of human face evolution. Romundina Fish is said to be a combination of primitive jawless fish and modern jawed fish. Scientist derived this conclusion by scanning skull of Romundina fish with X-Rays at ESRF- European Synchrotron.

Scientist discovered that Romundina had shorter forebrain and an extended upper lip. It thrived during Silurian and Devonian periods in Earth's history, but became extinct 360 million years ago. This Romundina fish was under placoderm type of fish.

The study further revealed that Romundina fish was 8 inch long with defensive spine and had flat crushing plate’s teeth. Its front being armor encased, backend was supple and had fins along with a sharp tail.

How did jawless creature turned into jawed creatures?

There are there steps of evolution of Romundina Fish. In the first step represented by Romundina, jaws evolved while a singular nostril  reached under the brain in jawless vertebrates was replaced by a solid floor under the brain and separate left and right nostrils opening on the face.

Nose located between the eyes and the skull stretched in front of it like a bony ‘upper lip’, forebrain remained small.

In second step, Nose extended while upper lip shrank making nose at front of face. However, forebrain still remained short. In the third and final step, jaw and forebrain increased as evident in contemporary awed vertebrates
