Huge 'sea monster' ruled ancient rivers
While dinosaurs controlled the land, a selection of reptiles reigned in the seas, and included dolphin-shaped ichthyosaurs and the Loch-Ness-Monster-like plesiosaurs. In the brand-new study, experts investigated another comparable beast-- extinct predators called mosasaurs, normally taken enormous finned marine lizards comparable and possibly even connected to present-day monitor lizards. The mosasaur fossils were unearthed beginning in 1999 from an open-pit mine in the Bakony Hills of western Hungary. The analysts discovered a number of 84-million-year-old specimens, ranging from little juveniles to adults 20 feet long that had limbs like a land-dwelling reptile, a flattened, crocodilelike skull, and a tail unlike various other understood members of the mosasaur family. 'The size of Pannoniasaurus makes it the largest known predator in the waters.

Whether these were marine or freshwater environments, it is [uncertain], however some finds in Japan suggests the latter," Makádi said. "Then sometime between this event and 85 million years before present — the age of our locality in Hungary — some primitive members of the already-marine mosasaurs adapted to freshwater life. Pannoniasaurus represents these. This scenario is very similar to the evolutionary history of cetaceans — whales, dolphins." |

Key:
- Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
- The Mean is meant to be an indicator of an individual's average comment sentiment.
- The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).
Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
