Superb collection, Roger - I have a few bits from Flamborough Head but you're not allowed to collect from the best area any more.

Thanks Tarquin. I'm done showing mine now. How about showing us some of yours?

 

Greetings from the Lake of Constance. Roger

Ludwiga you've got some SWEET sponges. Definitely some of the best I've seen.

I'm opening up my collection right now so I'll post a few.

Hindia saphaeroidalis

Naturally sectioned silicified speciman

2 in. - 5 cm. across the sponge

Birdsong Member
Beech River Formation
Wenlockian
Middle Silurian 424 to 430 mya

Beech River - Decatur, Tennessee

Named the Beech River formation for the Beech River, Decatur County,Tennessee. Consist almost exclusively of fine shales. The unit is highly fossiliferous, gray, yellow and bluish, and weathers into a white clay. Some beds of limestone exist. Thickness is 74 to 106 feet and divided into three crinoid zones. The Beech River formation is considered the basal unit of the Brownsport group. It is Silurian in age ( Niagrian)

The specimen is naturally sectioned and shows the exquisite silica preservation of this genus. As many are in the Birdsong member, this specimen is encased in a nodule of partially silicified country rock. Exceptionally large for this formation and one of the larger ones I have seen.

Amblysiphonella sp.

The top of this slab is covered with the cylindrical sponges:

The branched sponge in the middle is still attached to the erstwhile seafloor:

These sponges grew among phylloid algae, whose leafy thalli can be seen as paper-thin stringers in the side of the slab:

The slab as found in the outcrop (lower right):

Context is critical.

I have no links, but I can tell you how to do it:

All you need is digital camera, rotation table and a fossil! Decide how many shots you are going to use to create your animation. More shots - more smoothly will be animation (I use 36 shots). Then divide rotation table into equal sectors (in my case each sector = 10 deg.). Rotate your table from sector to sector and each time make a shot. In Photoshop create gif-animation. Upload it to TheFossilForum so we all can see animation you created ))))))
