squalicorax Posted February 21, 2013 Share Posted February 21, 2013 Hey all. I know some of you are experts on the whiskey bridge site Id like to post my identifications of all the gastropods ive found on my one trip there about 2 years ago now. Thanks for any insight you may offer. Ancilla staminea Architectonica Athleta Atwateria Buccitriton sp Cochlespiropsis Conus sauridens Distorsio personella Fusimitra Gegania antiquata Hesperiturris Lapparia moorgana Latirus Levifusus mortonopsis Michella Neverita limuli My Flickr Page of My Collection: http://www.flickr.com/photos/79424101@N00/sets Link to comment Share on other sites More sharing options...

erose Posted February 21, 2013 Share Posted February 21, 2013 Really nice! You have a mix of common to I think uncommon stuff there. I'm going to save the photos to my computer because they are better than any in my literature. And those weird little etchings(?) on that gastropod are too cool.

Herb Posted February 21, 2013 Share Posted February 21, 2013 (edited) Very nice specimens! Coco the site is Eocene. I think the coral is "Balanophyllia desmophyllum?", and the pelecypod is "Barbatia uxorispalmeri?" You got me on the gastropod etchings, but I think you are right with the bryozoan idea.

Uncle Siphuncle Posted February 22, 2013 Share Posted February 22, 2013 thats right coco, cook mountain formation. if i heard the story correctly, the bridge adjacent to the bluff was nicknamed whiskey bridge because the river separates a wet from a dry county, so all the drunks has to cross it to get their whiskey!

jkfoam Posted February 22, 2013 Share Posted February 22, 2013 thats right coco, cook mountain formation. if i heard the story correctly, the bridge adjacent to the bluff was nicknamed whiskey bridge because the river separates a wet from a dry county, so all the drunks has to cross it to get their whiskey! Ah, Yes. At one point in the not too distant past the county on the east side of the Brazos River was dry (that is, did not sell beer or liquor). It is also home to Texas A&M University. So the Aggies (students) and other residents of Brazos County had to cross the Brazos River to get their beer and other libations. Well, several liquor stores were in business right after you crossed the river into Burleson county. Hence, the bridge was nicknamed Whiskey Bridge. After Brazos voted in beer and liquor sales the liquor stores near Whiskey Bridge went out of business and disappeared.

jkfoam Posted February 22, 2013 Share Posted February 22, 2013 (edited) I think I can help you with some identifications. By the way, congratulations you have some really nice fossils. Ancilla staminea ; This speciment is Ancilla stamines puntulifera. The difference is that A.staminea has a shorter spire than the A.staminea punctulifera. Architectonica sp. ; This is, I believe, Architectonica (Solariaxis) elaborata (Conrad) Athleta ; These specimen are Athleta petrosus (Conrad) Atwateria; These specimen are not Atwateria but are Distorsio (Personella) septemdentata Gabb. Awateria does not have any dentation on the inside of the outer lip of the aperature. Buccitriton sp. ; You are right, these specimen are Buccitriton. There are two common species present at Whiskey Bridge. They are B. sagum and B. texanum. The difference between the two is that B. texanum has dentation on the inside of both lips of the aperature while B.sagum has dentation only on the inside of the outer lip. From your photo I cannot differentiate the two species. Cochlespiropsis ; These specimen are Cochlespira engonata Conrad. Distorsio personella These specimen are Distorsio (Personella) septemdentata. Characteristic of this specie are the seven teeth or bumps on the insise of the outer lip of the aperature. Fusimitra ; These are Fusimitra sp. There are two similiar species, F. perexilis and F. polita. They can be differentiated by the number of folds on the columella. F. perexilis has three folds and F. polita has four folds. If you clean the aperature of your specimen I think you can see the number of folds and get the right ID. Gegania antiquata (Conrad) What a great specimen. Lapparia moorgana : This is Lapparia mooreana (Gabb). Latirus ; This is Latirus moorei (Gabb). Michella ; This is Michella trabeatoides (Harris) Neverita limula ; The specimen on the bottom left is N. limula (Conrad), the specimen above it is not. It may be Tiburnus texanus (Harris). I cannot tell about the others with out a view of the bottom of the snail. Protosurcula ; This is Protosurcula gabbii (Conrad). Pseudoliva ; This is Pseudoliva vetusta carinata Conrad in Gabb. Sinum declive ; Congratulations, a really exceptional specimen. Turritella houstania ; This is Mesalia claibornensis Harris Unknown bivalve ; This is Barbatia (Barbatia) uxorispalmeri Stenzel and Krause Coral ; This is Balanophyllia desmophyllum Milne-Edwards and Haime Encrusting Bryozoan ; I have seen the marking on a number of fossils from Whiskey Bridge and other Eocene locations. I do not see any encrustation and I have always thought these were tracts made by snails trying to drill into the larger snail. Sort of marks made by attempts at predation. I hope this helps.

squalicorax Posted February 23, 2013 Author Share Posted February 23, 2013 Thanks everyone and most importantly jim for the detailed identifications. I need to get back to this site asap!

jkfoam Posted March 8, 2013 Share Posted March 8, 2013 I can understand your reluctance to settle on an identification. In examining your photos I see several candidates for identification. It could be an immature Distorsio (Personnela) septemdentata, or Bonellita parilis, or Coptostoma rameum, or Coptostoma ulmulum. When I compare your photos of the specimen to the fossils in my collection I am inclined to ID your specimen as Bonellita parilis Palmer. If I were you I would use this as a tentative identification. You can use Bulletins of American Paleontology, Vol. 7, pg 453, Pl 70, (by K.V.W. Palmer, 1937) and "Middle Eocene Claiborne Group Invertebrate Fossils, Stone City Bluff, Brazos River, Burleson County, Texas", by John and Barbara Emerson, Published by the Paleontology Section of the Houston Gem and Mineral Society as references for this identification I hope this helps Jim Knight 1 The Eocene is my favorite Link to comment Share on other sites More sharing options...
astron Posted April 11, 2013 Share Posted April 11, 2013 (edited) Protosurcula Pseudoliva Sinum declive Tiburnus Turitella sp Turritella houstania Unknown Bivalve. Coral? Striatolamia Encrusting Bryozoan? All Scales in cm Impressive assortment of fossils, Nathan!!! Congratulations and thanks for showing them. I have to thank much Jim, as well, whose the following description helped me to get the full id of my recently found Fusimitra gastropod: ''Fusimitra ; These are Fusimitra sp. There are two similiar species, F. perexilis and F. polita. They can be differentiated by the number of folds on the columella. F. perexilis has three folds and F. polita has four folds. If you clean the aperature of your specimen I think you can see the number of folds and get the right ID.'' A Greek friend of mine had suggested it's about Fusimitra and after the above I know the exact id: Fusimitra perexilis. Thanks again. Astrinos Edited April 11, 2013 by astron Astrinos P.

olivella Posted November 19, 2013 Share Posted November 19, 2013 Hi there, the Ancilla is Olivula staminea staminea (Conrad, 1833), which may not be an ancillid at all but is quite an interesting species. Ron Link to comment Share on other sites More sharing options...
