DPS Ammonite Posted June 16, 2017 Share Posted June 16, 2017 I think that is Durania austensis. See below my previous post from Aug. 5, 2016. I too do not see any texture that looks like that of a giant rudist. See photo of a 21cm diameter Durania austensis rudist from Plano Texas. It could have been feet long. Note that detail of the shell sort of looks like coral or wood grain. 1 My goal is to leave no stone or fossil unturned.

I also don't know what they were attached to or if there are different kinds that haven't been discovered yet.

Quer Posted March 30, 2018 Share Posted March 30, 2018 Yes, it's a rudist, belonging to family Radiolitidae (lower valve, very eroded). Note the cellular structure of the shell wall layer. http://www.paleotax.de/rudists/images/cells.gif Zig-zag decoration of the shell are frequent, but alas, not characteristic of a genus or species. ID of rudists is a tricky issue I think it's not possible with this specimen. It could be, for instance, Radiolites sp., like this one from wikipedia. You can find a very shyntetic overview about rudists here: http://www.ucmp.berkeley.edu/taxa/inverts/mollusca/rudists.php 4 Link to comment Share on other sites More sharing options...
Quer Posted October 11, 2018 Share Posted October 11, 2018 About three years ago I found this heavily water-eroded cluster of Radiolitidae as a boulder in a mountain torrent. Though its origin, and so its geological stage couldn’t be properly determined, it can be assumed it is Campanian, as the surrounding strata was. (I can’t help to think it is a Radiolites squamosus. Compare with this specimen ) After cleaning it, I’ve discovered that water erosion, tough bad for ID purposes, made of it a good piece in order to visualize the cellular structure of Radiolite’s shell layers, as said in the post above. I hope you enjoy the pictures. 3 1 Link to comment Share on other sites More sharing options...
Quer Posted December 31, 2018 Share Posted December 31, 2018 Recently I have found a rare piece (fragment) of Hippurites vidali showing a well preserved upper valve with well developed pustules. Pustules are not a constant feature of the species, some specimens showing them and most ones not at all. Vermiculate pores are clearly visible, too. Less likely, it could be Hippurites lamarcki, as both species are characterized by the large morphological variability presented by their characters, but size and strata data make me be inclined to the first option. 3 1 Link to comment Share on other sites More sharing options...
