fifbrindacier Posted January 26, 2017 Share Posted January 26, 2017 Hi everybody, i found some items in the department of Loir et Cher, region Touraine, at about 200 km at the south of Paris, France. The place where i found it covers from the Turonian to the Senonian (-91 to -83 my). Most of the sponges you find there are siphoniae or chenendoporae, but you can also find jereae, phymatellae or pachysalaxe. I think this one might be a chenendopora. It is in black silex and is about 7 cm wide and 6 hight. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

abyssunder Posted January 26, 2017 Share Posted January 26, 2017 Looks more like Siphonia /Hallirhoa, rather than Chenendopora, to me, but I'm not an expert in sponges.

Vieira Posted January 26, 2017 Share Posted January 26, 2017 Looks like a iron concretion to me I'm not a specialist. Wait for more comments. Link to comment Share on other sites More sharing options...

You're right @abyssunder, there is a resemblance. @viera has given another answer although i do not agree, to me this is a sponge, so let's wait for the experts' opinion.☺ Thanks, both of you for your answers.

GeschWhat Posted January 26, 2017 Share Posted January 26, 2017 How can you tell if it is a sponge? My first thought would have been a steinkern of some sort.

abyssunder Posted January 26, 2017 Share Posted January 26, 2017 According to the sponge morphology, the lower part of a sponge must have an attachment to the hard substrate (basal point) and in opposite side a hole (osculum), which I think are visible in the specimen in question, altered by a diagentic process. Also, interesting could be the radiating pattern of the circled with red areas. 2 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Coco Posted January 27, 2017 Share Posted January 27, 2017 Hi, Fifi, where did you find this ? I know Siphonia exists in "Centre" / "Pays-de-Loire" area and looks like your specimen, but I can't tell you more because I am not interested in and I don't have some information.
