Revisiting Spergen Hill, Indiana And Some Of Its Mississippian Micro-Fossils
dshamilla posted a topic in Micro-paleontology
This is my first "new topic" post to the FF, so I hope I'm doing this correctly. If you have a microscope or equivalent and a current or potential interest in micro-fossils, you might enjoy collecting at the following historic locality: Mississippian Salem Limestone, about 5 miles east of Salem, Indiana off Rt. 160; Spergen (Spurgeon) Hill, railroad cut (Manon RR) paralleling S. Harristown Rd, 0.75 mi north of Rt. 160; south end of Trackside Road; approximately 140 meters S of Harristown, Washington Co., Indiana; diminuitive fauna; Universal Transverse Mercator (UTM) coordinates: 16S 585024.- 9 replies

Went out to a railcut that slices through upper Racine formation. This locality is only 10 minutes from my house. I almost never visit it because of scarcity of fossils, however I was reading a paper that mentioned forams in chert and decided to take another look. Here you can see the beds dipping gently to the east. This is interreef strata. Closeby is/was a huge reef, now filled with garbage. Here is a chert nodule to be sliced up. Also, found a silicified coral and packed in my bag. Disturbed this guys slumber. Silicified Favosites

I had collected some fossils from Spring Branch, Texas from what I think is the Glen Rose fm near Canyon Lake and I'm wondering what all these little discs are. For some reason I thought they were called foraminifera but in looking on-line, I think that's not accurate. I'm not sure where I heard that these are called foraminifera. Perhaps someone told me that or, more likely, I misremembered something I read somewhere. In looking at Uncle Siphuncle's very, very, very helpful (Thank you. It's a must read!) pinned Comprehensive Guide heading this forum, it seems these little discs are calle

Found this stone in Dallas area creek, are these fusulinids? They are supposed to be abundant in limestone in Texas, you can faintly see rings in them like a slice of onion.

So I make slides of microfossils from ~ <1mm - 2mm. I use a glue that I make with food grade gum tragacanth and water as was recommended to me when I first started. However, I have always found it a bit annoying to make, get the consistency right and keep properly, especially as I haven't been able to find any definitive guides to this. I'm wondering whether any of you use gum tragacanth as well and have a ratio/recipe/advice for me? Or if anyone has had good success (long lasting, dries clear, secure, fossil safe) with any other type of glue? Thanks!

Upper Campanian foraminifera from Northern Germany. We found in the quarry of Laegerdorf near Hamburg. We think it is a Lituola. What's your opinion ? It is agglutinated and the specimens have such areal, multiple openings. See more of our finds at https://foraminifera.eu/loc.php?locality=Laegerdorf+Neue+Heidestrasse

Hi everyone I think I just found a new hobby With my latest fossil delivery I recieved quite a lot of microfossils & matrix vials as the world of microfossils was something that I have been long interested in. So a 2 weeks ago I finally ordered my first microfossils for which I reserved a special drawer in my archive cabinet. So here is a recapp of what I all got: 3 vials of permian material from Waurika, Oklahoma 1 vial of permian material from The red beds of Archer County, Texas 1 small vial of Conodont rich Mississippian material from the Chappel Limestone fo

Hi all, Need some help with this ID! I found this fossil years ago on a beach in eastern North Carolina and it's been a mystery to me since. The best answer I could come up with is that these might be some kind of foraminifera (maybe of the fusulinid variety, though these don't seem to have the tapering at either end), but I'm not sure how to go about researching other possibilities. My camera has a tough time with close-up pics, so this is probably as much resolution as I can get. Thanks in advance for the help!

Good morning all!- hope you are all healthy! I found these foraminifera (my first!!!) on April 20, but took my time fishing them out of some limestone, then meticulously cleaning and prepping them. Thanks to Clear Lake for suggesting, in my first post that it looks similar to Ozawainella ciscoensis-really appreciate it! They were all found in winterset limestone in Kansas City. Researching numerous references, I found it is far more complicated identifying them, so I'll send them to someone with more expertise in i.d.s! , and am leaving them as simply Foraminifera. I i.d. them und

Good morning all! While I was magnifying a shell which looks similar to a modern scallop I noted several discoid shaped objects in the matrix, so I cleaned them away and these are the best pictures I have so far. It measures 458um in diameter and is heavily crystallized. It is a very fossiliferous Pennsylvanian layer is all I can i.d. On the right track or way off? I have both sides depicted but the edge also has small "pores"/discreet nodules but can't get a pick of that yet. I will try to get some better pictures too. Thanks for looking and comments appreciated! Bone

This sample was stained by rose bengal solution. it was sampled from the intertidal zone in Apo reef natural park in mindoro, Philippines, around >5m depth. I'm confused on what species is this. I have no other pictures since we are under a community quarantine here in Manila so I have no access with my microscope.

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to com- 5 replies

Scientists use ancient marine fossils to unravel longstanding climate puzzle by Cardiff University https://phys.org/news/2020-01-scientists-ancient-marine-fossils-unravel.html Ancient marine fossils reveal how rising sea levels trapped carbon in the oceans preventing extinction-level global warming 14 million years ago. Fossil records suggest high levels of carbon was captured in ocean sediment. Significant volcanic activity had previously led to extinction level events.

I really like the shape to these. I have come across sites with photos of these but I can't seem to find any info about them such as what period they may be from. These microfossils are harder to research than they are to find...phewww.

To Rumi: Thanks for the ID of the elphidium ...The specimen in the last post was the largest I came across, it was about 1.5mm, all the rest are well less than 1mm. Are these smaller ones in this post of the same species? Thanks....

Hi Everyone, While this is not a fossil, it is a very large benthic foram that I am having trouble idenifying. Could anyone either tell me what this is, or point me to somewhere or someone that could help? This specimen is not whole, there is an outer ring on the other specimens like this, that is a slightly different pattern to the one seen here. These are up to 2 or 3 mm across. I have found them in VERY high abundances and need to figure out what they are. Thanks!

I'm heading down to Newport Beach, CA- south of LA. Does anyone know of micro-sites there with access? I'm also looking for information on local stratigraphy there. Any on-line resources that you could recommend? I'm new to collecting- and have been learning a lot from reading previous related posts. Your suggestions and advice are welcome.

What is the identification of the foraminifera present in this section? We suspect it as assilina but we think this should have a younger age instead. Thank you!
