Been meaning to post a few recently collected corals - I've collected several species with a view to polishing  sections but the naturally weathered ones (which I think are partly silicified) can show the detail just as well.
 

Here's the first:

Diphyphyllum lateseptatum, Namurian Great Limestone, Weardale.

Corallites 4-6mm diameter.

Dibunophyllum bipartitum. Namurian, Great Limestone
 

18 - 25mm across.

Dave, Colin, Malc - thanks all; looking out for photogenic and identifiable (I hope!) bits of coral livens up walks on the moors when there's usually not much else to collect.
 

My main ID source is Dorothy Hill's classic 1930s monograph on Scottish Carboniferous rugosa - not modern (I don't know of anything comparable that's more up to date) but covers much of what we get in NE England.

 

I'd be glad to put some in the Members Database if people think it would be useful. At least they're pretty!

Section through a Canininia cf. juddi, Great Limestone, Weardale.

(Ed. - I think this might be Koninckophyllum interruptum - quite similar in LS but the tabulae aren't perhaps quite as complete as in Caninia)

Shows wide, flat tabulae and typical bubbly dissepiments round the edge.

I'm still looking for a good transverse section but I think this is Caninia juddi:

Colin, that's nothing - see what happens when you google the coral genus "Amplexus"LOL.

It surprised me too Colin (although it rang faint bells from biology A level); what I really want to know is why a rugose coral is called Amplexus.

Aulophyllum fungites


 

Found as a convenient 3mm slice. 

Distinctive appearance with mass of tabellae and lamellae in the central region. Secondary septa half as long as primary septa (on the right in second pic.)

 

Widespread, but one of the less common corals in the Frosterley Marble (which is mostly the famous Dibunophyllum bipartitum).

That's a beauty, Gary - have you got an end view? - these horn corals all look pretty similar from the outside!



 

Dave - thanks, the camera perhaps tells lies a bit but supermacro is a good way to study the detail.

Another  Aulophyllum fungites (underneath a small Gigantopruductus).
 

Like the other, the voids are filled with calcite and the original structure is etched away except where it's been silicified.

 

20mm max. diameter

Came across this boulder in the middle of a stream - it's my dream colony of Lonsdaleia (ed: now Actinocyathus), taking up most of a block of Great Limestone 15x13x10" which  weighs 45kg.

(Muscles still recovering, but only had to get it 200yds across the stream and back to the van).



The silicified areas have naturally etched out and I think there's some
scope for acid prepping but the central core is calcite which would
polish well.

Gary, 45 kilos, unobtrusive at the end of the first line, nearly as heavy as the missus.
Dave - hope I can improve it, otherwise it can gently etch in the garden.
Colin, a calamity, I might try HCl (on the coral, not the chips)

Those are really nice Gary - not enough detail on the end shot to ID but could well be Aulophyllum

This unspectacular scrap could be a rarity - from the Great Limestone (basal Namurian), it looks like  Michelinia sp. - honeycomb structure with simple tabulae all the way across - which doesn't seem to have been recorded before. (Bit of crinoid in it too.)

It occurs much lower down in the Carboniferous and in one bed (Botany Limestone) much further up but seems to have been absent from the area in between times.

(Unless it's a piece of something common that I'm not seeing right...)

Edit: Michelinia it is - found a few more from this bed now...

Thanks, Bill.
Yet another Aulophyllum fungites, partially silicified again hence the etched out protrusions.

Does anyone know the mechanism of this sort of preservation? I'm assuming something similar to chalk and flint, with the silica from microorganisms and maybe some sponges but the details are hazy.

(Also posted in Recent Finds)

New to me - a very unusual Lonsdaleia from the Weardale Great Limestone.
(And with some green mineral staining.)

edit: I now believe this is a phaceloid growth form of Actinocyathus laticlavia, patches like this sometimes stick out of cerioid colonies.

Thanks, PJ & Geth - it'd be nice to see some different types if anyone has any - I'm planning to work my way downwards from the top of the Visean this year.

Here's a humble Syringopora - common enough generally but this is the first I've collected from the Great Limestone, near Frosterley again.

A couple more pics of the Syringopora - you can just make out V-shaped tabulae in the longitudinal section.
