minnbuckeye Posted February 7, 2019 Share Posted February 7, 2019 I just went through my bag of trilobits from this summer. Most are identified. I am getting better with time!! Here are a few Small pygidiums, all between 1 and 2 cm. These small non descript tails are hard for me to identify. If there are ones that stand out, let me know, and why you think so! That way I will know for next summer's specimens. They are numbered. Thanks, Mike Link to comment Share on other sites More sharing options...

minnbuckeye Posted February 8, 2019 Author Share Posted February 8, 2019 @Pumpkinhead That was my guess for #1, but normally the pygidiums for this species locally are 10x bigger! Are you saying Bumastoides for all? Link to comment Share on other sites More sharing options...

Are you saying Bumastoides for all? I'm not 100% certain, I was just going off of how effaced they are. I've seen some rather small ones though so from my experience the size is not implausible. If you don't mind telling me what the locality is I could try to find some references that could help Link to comment Share on other sites More sharing options...

piranha Posted February 9, 2019 Share Posted February 9, 2019 Juvenile trilobites are always smaller than adults. They match well with the example from Midwest Paleo. 2 Link to comment Share on other sites More sharing options...
