rew Posted January 29, 2021 Share Posted January 29, 2021 This graptolite is of Silurian age and is from the Rochester Shale, near Buffalo, NY. I hope someone knowledgeable about Paleozoic sea floor bric-a-brac can tell me what species this is. The main cucumber shaped colony is about 12 cm long. I'm guessing that this is in the genus Dictyonema, maybe Dictyonema crassibasale. but I'm no expert on this. 1 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted January 29, 2021 Share Posted January 29, 2021 I would agree with Dictyonema rather than Desmograptus which is the other common dendroid found in the Rochester according to my notes, but I don't know the species. Dictyonema retiforme, perhaps? Nice find. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
