How to use: Use the “get my location” button to search for localities near you. (Location services must be enabled for this to work.) Then click “Find Nearby Localities”. To find the layers, click on the button that looks like a bunch of squares stacked on top of one another. For a geologic map click “Microstat Geology”. (Layers may not load if zoomed out too far.) For the PBDB localities click “PBDB Localities”, or enable them both at the same time! I have not tested for countries other than the United States. You can also click the links on a locality to find a list of paleo-fauna. The map also appears to have removed the PBDB localities with incorrect coordinates. https://www.mindat.org/nearestlocs.php

I've noticed that despite the seeming abundance of Pleistocene deposits shown on geologic maps such as this one (https://txpub.usgs.gov/txgeology/), finding how or where they expose is much more difficult. On the geologic maps I use, when I hunt late cretaceous fossils, for example, late cretaceous exposures area all classified specifically with their own names (Eagle Ford, Ozan, Del rio clay, etc.). I can then research each individual formation, and it makes narrowing down spots much easier. It seems that for Pleistocene exposures, there are no "formation names" assigned to them. This makes it hard to make my research about them specific. Obviously some Pleistocene exposures must be better than others, and many probably have their own unique identifying characteristics, but I can't research any of that, as it seems all the Pleistocene occurrences on the map are just given blanket names like "terrace deposits " or "high gravel deposits". So, how do I direct my research to be successful for finding productive Pleistocene spots? Are there any Texans too who can tell me how the local geology looks with productive Pleistocene stuff? Any or all advice from anyone would help.

Hey Everyone, Ive been thinking that it’s about time I more heavily invested in my passion. Thusly, I’ve been curious about acquiring a gps. Does anyone have any recommendations for a good handheld gps that won’t break the bank? Is it possible to display USGS Topography and Geological survey maps? I don’t really want to spend more than $300. Any Response would be greatly appreciated. You guys are the best. With gratitude. -Nick.
