ynot Posted February 26, 2018 Share Posted February 26, 2018 Sponge, but I think the white frill is mineral not part of the animal. 3 Darwin said: " Man sprang from monkeys."

abyssunder Posted March 2, 2018 Share Posted March 2, 2018 Probably, the original material of the fossil was almost totally dissolved. The white external structure might be crystalline silica (amorphous or chalcedonic). 1 " 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.

Plantguy Posted March 4, 2018 Share Posted March 4, 2018 Is this the same locale/outcrop/formation as the plant material shown in the other post? Regards, Chris 1 Link to comment Share on other sites More sharing options...
abyssunder Posted March 4, 2018 Share Posted March 4, 2018 The fossil sponges in flint nodules from Texas were compared many years ago (J. A. Merrill, 1895) with the sponges in flint from UK. Here are some specimens from the flint pebbles (history collection), for comparative reason. pictures courtesy of Museum Of New Zeeland " 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.
