Im pretty happy with the condition and colors I was wondering whats the biggest hemi ever found or biggest personal hemi anyone else has found.

Extinct Gaits: How Did Pterosaurs and Synapsids Run?
Sightreader posted a topic in Questions & Answers
Howdy folks, me again with more silly beginner questions... I saw this video of a vampire bat running and wondered if pterosaurs - with their crutch-like folded wings - might have moved in a similar manner? Youtube: Vampire Bat on Treadmill I also saw this video of a Panda cub running. Might synapsids like Dinocephalians or Gorgonopsids - with those weird, “inturned” arms - have moved in a similar fashion? Youtube: Panda Bear Cub Running I’m guessing the answers to both of these questions is probably “no” - I would think that even a slight difference in a single joint or in the spine or hips would totally change an animal’s gait - but I really don’t know how the anatomy of such creatures compare. Are there extant species similar to either of these extinct animals that might give us an idea of how they moved? Thanks a ton for your patience! -
...over a few fields. With a bit of driving in between. Although spring has not officially sprung yet, I noticed that the farmers in my area are behaving like it's already arrived and are beginning to plow up some of their fields, so yesterday I figured I'd head out to the ones around Blumberg and Geisingen to see if their colleagues are doing the same. Sure enough, some of my favorite fields were freshly plowed. I also stopped in to the old clay pit just for nostalgia's sake. The productive layers there have been unreachable unter meters of debris for a long time now, but I managed to find a couple of weathered blocks which contained a few small ammonites. Prepping wasn't all that difficult, so I got most of the finds done today, although there are still a few bivalves to work on. Prorsisphinctes pseudomartinsi. ø8cm. Caumontisphinctes sp. ø 6cm. Pressastarte sp. 4,5cm. wide Ludwigella sp. Graphoceras decorum A small Prorsisphinctes sp. ammonite, Pygomalus ovalis echinoid and a rhynchonelloid brachiopod.
