Mahnmut Posted April 29, 2022 Share Posted April 29, 2022 Hello again, another find from my uncles garden (where he put fossils he found everywhere), so sadly no provenance info: Who can tell me what this is?

Tidgy's Dad Posted April 29, 2022 Share Posted April 29, 2022 (edited) Heliolitid coral, methinks. The lump on the top is actually the base of the coral from which it grew upwards and outwards and was anchored to the substrate. Edited April 29, 2022 by Tidgy's Dad 2 2 Life's Good! Tortoise Friend.

Paleorunner Posted April 29, 2022 Share Posted April 29, 2022 I don't know what kind of coral it is, but what Adam @Tidgy's Dadsays is clear. The photo shows the anchor point and the circular lines of growth. Missing to see a photo from above. 1 Link to comment Share on other sites More sharing options...

Not so sure about this part. These coral like to encrust things too. 1 Link to comment Share on other sites More sharing options...
Mahnmut Posted April 30, 2022 Author Share Posted April 30, 2022 (edited) Thanks! here is the view from the other side, least well preserved and also with a bump. Heliolitid looks convincing.

They do sometimes have bumps and protrusions and looking at the new photo, the growth areas seem to suggest this is the underside, but having a big knob in the centre on both the top or bottom seems to suggest one of them is some sort of 'stem'.

Mahnmut Posted April 30, 2022 Author Share Posted April 30, 2022 Sorry, could have thought about that. In most parts of the surface the detail is close to invisible, here is the best I can find: 1 1 Try to learn something about everything and everything about something Thomas Henry Huxley Link to comment Share on other sites More sharing options...

Mahnmut Posted April 30, 2022 Author Share Posted April 30, 2022 So I can call my beastie here Pachycanalicula? If these invisible pores are pachy, what would a Leptocanalicula look like? I think your pic shows a negative of what I got here? or is that a convex-concave optical illusion?

Mine was just an example I had handy . 15 minutes ago, Mahnmut said: I think your pic shows a negative of what I got here? You are correct, its a negative.
