Hello, everybody!

I have been sorting through my wenlock limestone material, Middle Silurian and have a couple of personal problematica. 

I am wondering if any of you brilliant folks could help me out. 

Here is an object which seems to be an epibiont on a Favosites coral. 5 mm long and about 1.5 mm diameter at the widest. 

Is it a cornulitid ? Or a single corallite of Aulopora? Something else, maybe?

And another one? On a solitary rugose coral. 3 mm x 1 mm.

And an example of Aulopora from Wiki to compare :

And a cornulitid that looks a bit similar :

I would be very grateful for any help. 

Then there is this. Is it the worm Keilorites? 

Length 1.9 cm, width 2.5 mm max.

Another conversion disaster. Fortunately we caught it in time. :)

While we wait for the brilliant folks to rouse I'll go with cornulitid.

Those are really tricky! Without ultrastructure, you might not be able to decide between cornulitid and auloporid, though a single auloporid corallite is unusual - it would probably have to be a failed colony.

Haven't a clue about the second one!

 

Here's Aulopora on a Wenlock Propora, individual bits are about 4x1.5mm.

Thank you, Tarquin, your input is always most appreciated. :)

Your photo is helpful too, the blobby second object I posted looks quite like the auloporid linking 'tube' structure bottom left to bottom centre of your photo.

Aulopora has a definite growth habit,fide eg. Scrutton(1990,non encrusting) and Helm(encrusting(1999)

Thanks, everybody. 

For now I'll just label them as possible Aulopora, possible cornulitid and a  possible worm or something else entirely! :D

I thought that these could be difficult. :)
