A final reminder about this week's quiz question before the answer is revealed tomorrow. You've been asked: How did Triceratops grow its brow horns? From their bases or from their tips?Today's entry is a dubious Tyrannosaurid:
Name: Deinodon Pronunciation: Dy-no-donMeaning of name: "Terrible tooth"Species: D. horridusSize: Uncertain due to a lack of fossils.Family: Deinodontinae (a subfamily of Tyrannosauridae)Diet: CarnivoreFirst fossils found: Known only from a set of teeth discovered in the Judith River Formation of Montana. Named by American palaeontologist, Joseph Mellick Leidy, in 1856. It's possible that Deinodon and Gorgosaurus may be the same species.Lived: 77 million years ago during the Campanian stage of the Late Cretaceous in what is now the western United States.

Tix Mascot , LadyPorthos , well done for correctly guessing the answer to this week's quiz question. You were asked: How did Triceratops grow its brow horns? From their bases or from their tips?Answer: From their bases. Until recently, we only had skulls from adult Triceratops, however, over the past three years, a number of skulls belonging to juveniles have been discovered in the Hell Creek Formation of eastern Montana, and the horns on these specimens provide clues about how the small bony stubs above each eye on the young animals transformed into the slightly S-shaped, 3-foot-long horns in adults. Even newborns had tiny forward-pointing horns. Juveniles had short, thick horns that curved upward and slightly back. In adults, the brow horns are thick and curve forward at their base, but they retain an upward curve at their tips. This growth pattern suggests the horns grew from their bases. The horn on the snout started as a separate bone that later fused to the skull. One-third of each brow horn was hollow, rendering them susceptible to damage if they were used for defense (if broken, the horns didn't grow back). Therefore, it's more likely their primary functions were species recognition and sexual display.

Name: ElaltitanPronunciation: Ee-lal-tie-tanMeaning of name: "Elal giant", after the god of the Tehuelche people.Species: E. lilloi Size: Uncertain due to a lack of fossils, but is estimated to have measured between 18 and 20 metres long and weighing around 23 metric tonnes.Family: Uncertain. Likely Titanosaurid.Diet: HerbivoreFirst fossils found: Known only from vertebrae and parts of the pelvis and the fore and hind limbs discovered in the Bajo Barreal Formation of southern Argentina. Originally named as a species of Antarctosaurus in 1979, before being renamed as a species of Argyrosaurus. Was eventually recognized as a new genus and named Elaltitan by Philip D. Mannion and Alejandro Otero in 2012.Lived: 96.5 to 89.3 million years ago during the Cenomanian and Turonian stages of the Late Cretaceous in what is now southern Argentina.

Thanks! I worked on a farm during the summer of 1977. If I remember correctly, the farmer once told me that cows and bulls also grow their horns from the base, so this is probably where I got the idea from.
