Name: ChirostenotesPronunciation: Ky-ro-sten-o-teezMeaning of name: "Narrow handed"Species: C. pergracilisSize: Estimated to have measured around 2.5 metres long, 1.5 metres tall and weighing 40kgs.Family: CaenagnathidaeDiet: Uncertain. Possible omnivore.First fossils found: Known only from a single, partial skeleton discovered in the Dinosaur Park Formation of Alberta, Canada, and named by American palaeontologist, Charles Whitney Gilmore, in 1924. (Hands found in 1914. Feet found in 1932 and named Macrophalangia, lower jaws found in 1936 and named Caenagnathus). In 1988, it was discovered that all the fossils actually belonged to the same animal, so Chirostenotes became the official name.Lived: 76.5 million years ago during the Campanian stage of the Late Cretaceous in what is now western Canada.

Today's entry is a Sauropod with spines on its neck: Name: BajadasaurusPronunciation: Bah-jar-da-sore-usMeaning of name: "Downhill lizard", in reference to the Bajada Colorada Formation where its fossils were discovered.Species: B. pronuspinaxSize: Estimated to have measured between 10 and 13 metres long. Height and weight uncertain.Family: DicraeosauridaeDiet: Herbivore. Likely fed on both high and low-growing vegetation.First fossils found: Known only from a single, partial skeleton discovered in the Bajada Colorada Formation of northern Patagonia, Argentina, in 2010. Named by Argentinian palaeontologist, Pablo Gallina, in 2019. The most striking feature of this Sauropod are the elongated spines extending from the back of its neck. Current theories regarding these spines is that they may have been used either for defense or display. Another theory is that the spines may have supported a skin sail used to help control body temperature.Lived: 145 to 132.9 million years ago during the Berriasian and Valanginian stages of the Early Cretaceous in what is now northern Patagonia, Argentina. |

I have a feeling it may have supported a sail like a few others have. Kind of creep looking in the drawing.

Digression: Which is the best place (museum etc) to visit for dinosaur related matters? I think that depends on what country you're in. |

Closest to me is the Field Museum. I've been there but years ago. No idea where the best one in the US is but this is a pretty good one. www.fieldmuseum.org |
