willtexas07 Posted October 18, 2015 Share Posted October 18, 2015 Found some fossils and some partial fossils. I am pretty new at this and I am interested in trying to determine what species they are. Thanks for any input and for looking! Link to comment Share on other sites More sharing options...

Uncle Siphuncle Posted October 18, 2015 Share Posted October 18, 2015 Looks like you are still canvassing the Georgetown and Del Rio fms. The scallop is Neithea (I'd have to look up species). I think I see some Gryphea mucronata oysters which are known to occur in the mid to upper Del Rio, but I'm not sure of their entire range. I see a partial nautiloid that I'll tentatively call Cymatoceras. The ammonite, in my opinion, is the prize of the bunch. I don't find many planispiral ammos in the Kdr/Kgt sequence locally. Well done. 1 Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...
willtexas07 Posted October 19, 2015 Author Share Posted October 19, 2015 Thanks a ton Uncle Siphuncle! I can always count on you. I am very glad you are here to provide expert local knowledge to newbies like me. I have indeed been back in the Georgetown formation. It is right down the hill from my house. A 3 minute walk down the hill and I am on it. The ammonite is pretty cool. I disturbed a lot of spiders turning over rocks looking for it! What layer is your favorite to work locally? Are there any good places to access the Austin Chalk? Thanks a ton! Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted October 19, 2015 Share Posted October 19, 2015 I like everything except Edwards and Buda locally. There is lots of Austin from NE to western San Antonio, but it is only sporadically productive. There are a few members exposed locally, including Atco and Dessau, I believe, but there could be others. I haven't yet learned to ID members by ammonite zones. Lithology varies greatly. If you PM me where you live, I may be able to direct you to a local exposure nearby, but patience is your best tool when working the Austin. At a minimum you'll have an idea what the lithology looks like as you explore around town. Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils."
