Kosmoceras Posted June 5, 2012 Share Posted June 5, 2012 (edited) Went to a chalk quarry yesterday and came back with a lot of fossils. I have a lot of prep ahead of me. It rained on the way to the quarry, but when there it was decent weather so I could collect without getting wet. This morning I was preparing a few brachiopod shells. They need some matrix taken off, and some clearing out with a fine needle, but other than that I think they are looking good. As more fossils get done I will update this topic.All the best,Thomas.

Malcolmt Posted June 5, 2012 Share Posted June 5, 2012 Very nice.. not a lot of prep needed.......... any chance you found any trilos on your hunt.......... Link to comment Share on other sites More sharing options...
Kosmoceras Posted June 5, 2012 Author Share Posted June 5, 2012 Very nice.. not a lot of prep needed.......... any chance you found any trilos on your hunt.......... Thanks. I am not sure if trilos can be found in Cretaceous chalk, but I would love to find trilos some day. Maybe in Sweden this summer I will find some.

Auspex Posted June 5, 2012 Share Posted June 5, 2012 A couple of examples of a burrow - Terebella lewesiensis which are lined with fish scales. Lined with scales? Cool! Do they know what sort of critter made the burrows?

squalicorax Posted June 5, 2012 Share Posted June 5, 2012 Excellent brachiopods. I have a soft spot for their diversity My Flickr Page of My Collection: http://www.flickr.com/photos/79424101@N00/sets Link to comment Share on other sites More sharing options...
Kosmoceras Posted June 5, 2012 Author Share Posted June 5, 2012 Lined with scales? Cool! Do they know what sort of critter made the burrows? Hi Chas, Terebella lewesiensis was a worm I believe. They sometimes used fish bones/scales, and sometimes plants to line their burrows. I have a couple more examples I will post, but they have not been taken out of the bag yet.

Kosmoceras Posted June 5, 2012 Author Share Posted June 5, 2012 Excellent brachiopods. I have a soft spot for their diversity Thanks, came back with about 50 yesterday. Most are free of matrix, but I prefer ones sitting in a small block. Link to comment Share on other sites More sharing options...
Kosmoceras Posted June 5, 2012 Author Share Posted June 5, 2012 A chalk ammonite - Schloenbachia sp. Ammonites are rare from Totternhoe, but I managed to get a fragment. Link to comment Share on other sites More sharing options...
erose Posted June 5, 2012 Share Posted June 5, 2012 Brachiopods are also few and far between in the Texas chalk. Maybe a half dozen(?) species in the entire Texas Cretaceous. You have two nice ones there. Are there other genera & species besides those two? Link to comment Share on other sites More sharing options...

You have two nice ones there. Are there other genera & species besides those two? There are several species, some of which I have found are - Gibbithyris semiglobosa, Carneithyris sp, Tetrahynchia tetrahedria, Epithyris oxonica There might be a couple more.

CH4ShotCaller Posted June 10, 2012 Share Posted June 10, 2012 Thanks Lloyd, it was a very successful hunt. Attached is a picture before packing the load into the car. That looks like a heavy load, hope you didn't have to hike far with all that! Nice pictures, is this on the coast?

Dave pom Allen Posted June 10, 2012 Share Posted June 10, 2012 (edited) Hi Chas, Terebella lewesiensis was a worm I believe. They sometimes used fish bones/scales, and sometimes plants to line their burrows. I have a couple more examples I will post, but they have not been taken out of the bag yet. I always wondered what these were , never really thought that they might be a lined burrow.I always assumed they were the excrement of larger fish or possibly from a seal. Thanks for that heres a photo of similar things that i have but not as old. Edited June 10, 2012 by Dave pom Allen Link to comment Share on other sites More sharing options...
Auspex Posted June 10, 2012 Share Posted June 10, 2012 Dave, If the cross section shows that the coarse material runs throughout your items, they could well be coprolites (it seems unlikely to my mind that an empty burrow would fill with debris like that, but I suppose it's possible). If the coarse material is limited to the outer walls, then I would vote for it being a lined burrow.

Kosmoceras Posted June 11, 2012 Author Share Posted June 11, 2012 (edited) That looks like a heavy load, hope you didn't have to hike far with all that! Nice pictures, is this on the coast? Thanks, it was only about a mile of so, not too far. An no, this is not on the coast, it is inland UK at a quarry, 72 miles to be exact. I always wondered what these were , never really thought that they might be a lined burrow.I always assumed they were the excrement of larger fish or possibly from a seal. Thanks for that heres a photo of similar things that i have but not as old. It does look similar I must say, but I would agree with auspex, if it is fish scaled lined throughout, it is most likely a coprolite, if only on the other edge, a burrow which has been lined with fish scales.
