<p>In dinosaur-era seas, a kind of sea monster lived. These fish-shaped marine reptiles grew to enormous sizes in a span of just 2.5 million years, a new study has found. &nbsp;</p>

<p>The discovery says that these creatures like ichthyosaurs grew to gigantic sizes quickly. &nbsp;</p>

<p>The new species has been named Cymbospondylus youngorum by the team, said a report in the journal ‘Science' on Thursday. &nbsp;</p>

<p>The marine reptile, which was big-jawed, used to live around 247 million years ago during the Triassic period.&nbsp;&nbsp;</p>

<p>This full-grown creature would have a nearly 6.5-foot-long skull and be measured over 55 feet, the researchers found. &nbsp;&nbsp;</p>
