  1. I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!

    Adam's Early / Lower Devonian

    The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids. By the end of the Devonian , several of these groups are extinct or severely reduced in importance and brachiopods never quite recover. Also, the Devonian is the last time we see trilobites with such variation, large sizes and numbers and orthocerids too are much more uncommon after the rise of the goniatites. The massive tabulate coral reefs also disappear after the Devonian. Fascinating period and I hope to share some of its wonders with you. Equally, a lot of this is rather new to me, so I would be very grateful for any assistance, corrections or further information on my specimens. Thank you. The Early Devonian epoch is split into three stages, so let's start with the first of those, the Lochkovian, that began about 419 mya and finished roughly 411 mya. I have been sent a nice selection of brachiopods from the Kalkberg Formation, Helderberg Group by the Mighty @Misha, mostly. But the kind gentleperson also sent me this fascinating little bryozoan hash : It is dominated by fenestellids, which is usually the case in the Devonian, but other orders sill occur. These ones, I think, are Fenestella, but there are so many species in the formation that I wont take a guess as to species : Not sure what this one is ;
  3. Last year, while looking around a quarry in Upstate NY (Middle Devonian, Moscow fm), I stumbled across a trilo-bit I have had trouble placing. It’s some kind of phacopid, but not an Eldredgeops, and it just doesn’t feel like a Greenops. Found at a site with associated Dipleura dekayi, Greenops, Eldredgeops, Tornoceras, orthocerid nautiloids. The first photo is the mystery bug in question, followed by a Greenops and an Eldredgeops from the same site for easy side-by-side comparison. The final picture is a close visual analogue I’ve found online, though it is Moroccan and I am unsure of the location of origin.

    Trilobite ID

    Found what looks like a Phacopid trilobite here in Missouri. It was found weathered, but I believe it's from the Bailey Limestone. Is there a fauna list or reference anyone has on these trilobites they could share?

    Phacops sp. from Morocco

    Unknown species of Phacops trilobite from Morocco. Has beautiful eyes and nose! All small details of the eyes are preserved nicely. Huge crack is crossing from the left pygidium to the right middle of thorax segment, which is very common in Moroccan trilobite.

    drotops megalomanicus?

    Just curios as to what species this is I looked at phacops but non seem to have such defined bumps for a better word also the eyes don't match up at least not to the ones I have looked at. Again questioning this id because what is exposed so far is rather small 0.86" by 0.80" and the size of the matrix block is 2.51" by 2.34" Also I am prepping this currently so not fully exposed yet don't know if that will hinder the possibility of confirming an id. Thanks Matt

    ENROLLED TRILOBITE

    Quite a large specimen even for this quite big species. The length given is of the animal along the centre of its back, not the diameter.
  24. Kane

    Coltraneia oufatenensis

    Entry includes detail of eye lenses. One of the defining characteristics of this particular species, apart from the impressive eyes, is the convex nature of the anterior portion of the glabella.
