corals

achwirot

Hello everybody. From last few weeks I was searching carboniferous limestone. I found many brachiopods , some gastropods and corals. Last group isn't easy to classify. I'd like to ask you for correction.
1a and 1b:Corals are 11 cm high and about 1 cm diameter.
2a and 2b: Probably Siphonodendron sp. 5-6 mm diameter.
3 : Syringopora 2mm diameter.
4a and 4b: ? diameter 15 mm and 55 mm long.
5a and 5b: Siphonophyllia or Caninia 95mm long and 50 mm diameter.
6: Lithostrotion sp. ? 5mm diameter
7: Alveolites sp. diameter 1/4 mm pores
8: Lithostrotion sp. 10mm diameter

It is difficult for me to help you identify those corals as the pictures aren't clear enough to check features such as the columella, the number of septa, tabularium diameter, etc. However, this identification key that might be of some use to you, it relates specifically to Carboniferous Siphonodendroid and Lithostrotionid corals.

Unfortunately, it would not upload for some reason, so I will put it in another post

Ok I'm sorry that the formatting is all over the place, but you get the idea

Does 4a not look like calamites?

Shows what i know!

But looks similar!

I'd say 5a/b is Caninia. I've a few of them collected when i was a kid. Some of them look like they fell over in the curent and started to grow in diff directions. One I have is nearly a foot long. some of the other look like Lithostrotion to me anyway. 7 looks like a bryazoan(sp)
