Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelgill (Skelghyll) in Cumbria, Northern England. It seems to be a tabulate coral, but I can't find any listed for this location, only mentions of small, rare, rugose corals. It has the star shaped corallites of a Heliolitidid, but seems to be tightly packed together like a Favositidid. A couple of species of Palaeofavosites seem to be close and are a bit star-shaped,, but anyone know any better? @TqB@piranha hmm who else? The coral bit, an external mold, is a maximum of 3.5 cm across and each corallite up to 2 mm.

A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya. Another angle :

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 ;

I recently required this lovely little brachiopod from the kindly @connorp It was found in the 'Butter Shale" layer of the Liberty Formation at the Southgate Hill road cut, St. Leon, Dearborn County, Indiana. This is the layer that is famous for the multitude of tiny, usually enrolled, Flexicalymene retrorsa minuens trilobites. But it doesn't contain many brachiopods apart from the occasional lingulid as far as I can ascertain . So this specimen has likely come from a higher level of the Liberty, or possibly from the Lower Whitewater overlying that. Or, conceivably, it comes from the underlying Waynesville Formation which is not necessarily always lower if the beds are dipping and the area searched was nearer to the road. Or it may have been dropped by someone. Anyway, I've checked all my literature and can't find a match, unless someone's got a photo or document that shows the posterior view / interarea of Austinella scovillei which is sort of my last faint hope. It closely resembles other brachiopods from the Cincinnatian, but not any from these formations. Any help or leads would be most gratefully received. The specimen is small; 1.4 cm wide along the hingeline and is subequally biconvex. Thanks for looking!

From the album: Brachiopods of Platteville/Decorah Twin Cities Minnesota
Vinlandostrophia (formerly Platystrophia) trentonensis. Practically the only Minnesota Decorah formation orthid that I know of that have wings (Strophomena filitexta from a different family have wings but not as pronounced). Rare - hadn't found any 100% intact adult specimen yet as one wing always seem to be broken off.-
