Excerpt:

Xenoceratops (meaning "alien horned-face") had massive spikes at the top of its head, two hooks jutting from its forehead, and a ruffled shield around its neck. copyright Julius Csotonyi 2012. Paleontologists in Canada have discovered fossils of a new 2-ton, 20-foot-long horned dinosaur that roamed the Earth about 80 million years ago. And its headgear would've put on quite a show for the ladies. The dinosaur, a distant cousin of Triceratops called Xenoceratops foremostensis, is one of the oldest specimens known to date of the ceratopsid group. The beast's name, Xenoceratops, translates to "alien horned-face," referring to its strange pattern of horns on its head and above its brow, and the rarity of such horned dinosaurs in this part of the fossil record. 'The bits of anatomy that are preserved on this species give us a lot of great information about how horned dinosaurs as a group evolved.

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.
