Tidgy's Dad Posted September 1, 2018 Share Posted September 1, 2018 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. 1 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Fortunately we caught it in time. While we wait for the brilliant folks to rouse I'll go with cornulitid. 1 Link to comment Share on other sites More sharing options...

TqB Posted September 2, 2018 Share Posted September 2, 2018 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. 3 Tarquin Link to comment Share on other sites More sharing options...

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. Life's Good! Tortoise Friend.

doushantuo Posted September 2, 2018 Share Posted September 2, 2018 Aulopora has a definite growth habit,fide eg. Scrutton(1990,non encrusting) and Helm(encrusting(1999) 1 Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted September 3, 2018 Author Share Posted September 3, 2018 Thanks, everybody. For now I'll just label them as possible Aulopora, possible cornulitid and a possible worm or something else entirely! I thought that these could be difficult. Life's Good! Tortoise Friend.

Tidgy's Dad Posted February 21, 2023 Author Share Posted February 21, 2023 I am now fairly certain that the first one is Cornulites serpularius as I have found and seen others. The second 'wormy weirdie' is still a mystery. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
