Happy New Year 2020

Hi all.  A Theropod Database update is online, with the main additions being troodontid information and info from the Hayashibara Museum of Natural Sciences Research Bulletins 1-3.  I love these publications and wish more like them existed for other collections.  They detail the expeditions into Mongolia with exact discovery dates and field numbers for taxa like Nomingia, Elsornis and Aepyornithomimus, and tons of still undescribed specimens.  It's amazing just how many ornithomimosaurs are known from the Bayanshiree Formation for instance, when only the Garudimimus holotype has been described.  There are over twenty more including the sort-of-described "Gallimimus" "mongoliensis" specimen IGM 100/14.  So often for new taxa, especially those from the Jehol biota, no information is provided in the description as to when the specimen was discovered.  I get that many are found by non-professionals and given to museums, but at least say "the specimen was given to the museum on x-x-xx by someone who said it was excavated around year y."  Next up, halszkaraptorine and dromaeosaurid updates...

  1. Happy new year! I'm very much amazed by all the updates, do you have a pdf of this publication? I searched online, but nothing came up.

  2. Simply the very best of this new year Mickey, all my best to the best, Chris

  3. A comment on YFGP-T5200 and YFGP-T5201 (mentioned in Brougham 2014). I have carefully first-hand examined both in 2015: the former is a chimera of two partial specimens, with fake bones and all feathers printed; the latter is an Anchiornis-like form that I hope to formally describe in the future (sadly, that project is currently in stand-by).

    1. What is the Yizhou Fossil and Geology Park like? Is it simply a collections building, or is there an actual museum and Google Maps doesn't recognize it?
