Tidgy's Dad Posted November 27, 2018 Share Posted November 27, 2018 I disagree with you on one point, Ralph. I think they're pretty darned sexy trilobites! Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

That is another nice thing with them, usually I just split and cut, all done with the prep. 1 Link to comment Share on other sites More sharing options...
Paciphacops Posted November 27, 2018 Share Posted November 27, 2018 More nice bugs! I have been splitting some of my matrix recently after extensive soaking, but no pictures yet. I was waiting on a new relay lens so I could use my DSLR directly on my scope. Got the 0.5x lens, but the magnification is still too much due to the smaller micro 4/3rds chip. Have you noticed the best preserved bugs seem to always fall part way across the edge of a block? Must be Murphy's law at work.

Nimravis Posted November 28, 2018 Author Share Posted November 28, 2018 While I was opening Mazon Creek concretions, I was soaking some matrix that I had already split into smaller pieces to see if I could split them farther. Here are some of the better finds- Part and counterpart Part and counterpart Here are some pieces that I split open this afternoon. Here is a real tiny one- 3 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted November 28, 2018 Share Posted November 28, 2018 Nice! And i love some of these teeny, but beautifully preserved ones. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted November 29, 2018 Share Posted November 29, 2018 Nice. I always love the ones with the 'shell' still preserved, but it's so fragile! Some of those look great. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

I agree Adam, I found a large one earlier this year (See Below) and when I split it, the Exoskeleton stayed mostly intact. 5 Link to comment Share on other sites More sharing options...

Nimravis Posted December 1, 2018 Author Share Posted December 1, 2018 Here are a few finds from “soaking” tonight. I try to only show near complete specimens, but the amount of partial trilobites is +10 fold that of complete ones. I found my largest Agnostid trilobite tonight, I just wish that it was complete. This piece is about 15 times larger than any other Agnostid trilobites that I have found. I believe that this is Aspidagnostus rugosus. Here are some Aphelaspis brachyphasis. 5 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted December 1, 2018 Share Posted December 1, 2018 WOW! That Aspidagnostus is enormous! What a monster! Love some of the others, too, I like the darker brown layers that have lots of pieces in them. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Bet you were pleased with that agnostid, though. I know it's a partial, but I think that species is pretty darned rare there? Your first one of those, as far as I recall. Nice. Life's Good!
