rew Posted October 2, 2019 Author Share Posted October 2, 2019 I haven't done a midweek bonus trilobite in a while so here's one. Trilobite #73 is Metacanthina issoumourensis, a common Early Devonian acastid from Jbel Issoumour, Morocco. This is an above average size specimen, with no restoration. 4 Link to comment Share on other sites More sharing options...
rew Posted October 5, 2019 Author Share Posted October 5, 2019 Trilobite of the week #74 is Minicryphaeus giganteus, an early Devonian (Pragian) bug from Oufaten, Alnif, Morocco. It is distinguished by its triangular rostrum. 6 Link to comment Share on other sites More sharing options...
rew Posted October 9, 2019 Author Share Posted October 9, 2019 This week's mid week bonus trilobite, #75, is a Devonian proetid from Ofaten, Morocco, Cyphaspis walteri. Everybody likes this bug. 3 Link to comment Share on other sites More sharing options...
Ash Posted October 10, 2019 Share Posted October 10, 2019 This thread isn’t getting the attention it deserves. Come on guys and gals, leave a comment if you look at this thread. I feel it’s been a long while since TFF had a thread of this caliber.. Mate, you have an awesome collection. Anything from Australia?

rew Posted October 11, 2019 Author Share Posted October 11, 2019 I have no Australian trilobites. (A couple of crinoids, yes, but no trilobites.) Australia has some awesome Cambrian bugs, but alas, so far as I know they come from a site that is now off limits to commercial collecting. I get the most comments when I misidentify something, which is often enough. Link to comment Share on other sites More sharing options...
rew Posted October 12, 2019 Author Share Posted October 12, 2019 The long spined Cyphaspides trilobite on page 5 of this long thread now has a formal name. It's Cyphaspides nicoleae. Link to comment Share on other sites More sharing options...

rew Posted October 12, 2019 Author Share Posted October 12, 2019 Official trilobite of the week #76 is a common Devonian Cheirurid from Laatchana, Morocco, Crotalocephalina gibbus. It may be common, but it's also a pretty cool trilobite. The nice thing about Morocco is that they have some cool bugs you can buy without remortgaging your house. 3 1 Link to comment Share on other sites More sharing options...

I bet it would cost an arm and a leg to acquire such a specimen! I agree with @Ash, your collection is immaculate.

Mark Kmiecik Posted October 14, 2019 Share Posted October 14, 2019 I have been following this thread and have seen every page. Didn't want to interrupt the flow by posting, and was busy wiping drool off the desk. Keep the goodies coming. I'm lovin' it. Mark.

rew Posted October 17, 2019 Author Share Posted October 17, 2019 The mid-week bonus trilobite is a bit late this week. It is #77, Amecephalus idahoense a Middle Cambrian trilobite from the Spence Shale of Miner's Hollow in the Wellsville Mountains of Utah. 2 Link to comment Share on other sites More sharing options...

rew Posted October 20, 2019 Author Share Posted October 20, 2019 This thread started with my Meadowtownella crosotus specimen, formerly Primaspis crosotus. Trilobite of the week #78 is my other member of the genus, Meadowtownella trentonensis, an Ordovician Ondontopleurid from the Walcott-Rust quarry in Russia, New York. 3 Link to comment Share on other sites More sharing options...
rew Posted October 20, 2019 Author Share Posted October 20, 2019 BTW, one advantage of photographing my trilobites is that, particularly for the smaller ones (the M. trentonensis is only a bit over 1 cm in length) I can see details that aren't visible to the naked eye. I didn't know this specimen has fringes of short spines on the free cheeks until I took the pictures. (This feature is more visible on M. crosotus.) 1 Link to comment Share on other sites More sharing options...
rew Posted October 27, 2019 Author Share Posted October 27, 2019 I still have the magnifying macro lens on my camera so it's going to be little trilobites until I get around to changing the lens. This week's trilobite, #79, is a Late Ordovician proetid from the Bobcaygeon Formation of Bellesville, Ontario called Cyphoproetus milleri. This humble bug is the only Ordovician member of the Proetidae in my collection. 2 Link to comment Share on other sites More sharing options...
rew Posted October 27, 2019 Author Share Posted October 27, 2019 A question for any proetid experts out there: Do you consider the Phillipsiidae to be a distinct family from the Proetidae, or the former to be a subfamily of the latter? Link to comment Share on other sites More sharing options...

rew Posted October 27, 2019 Author Share Posted October 27, 2019 What distinguishes Cyphoproetus milleri from Cyphoproetus wilsonae? Link to comment Share on other sites More sharing options...
rew Posted October 27, 2019 Author Share Posted October 27, 2019 I noticed that Sam Gon's web site doesn't list Phillipsiidae as a family and lumps all it's genera into Proetidae. Hence my question. I realize that the genera listing on his site may be outdated in some respects. Link to comment Share on other sites More sharing options...

rew Posted October 31, 2019 Author Share Posted October 31, 2019 I have a mid-week bonus trilobite, #80, Bathyurus extans, a Middle Ordovician proetid from the Black River Group of Watertown, New York.
