Selecting Beach Rocks and Micro Fossils For ID

Recommended Posts

This is a completely new area of interest for me, but I find scanning for microfossils addictive.  I got some vinegar and plan on processing some beach rocks (East Central Florida) that I picked up because I could see easily see some small fossils on the surface and assumed there would also be micro fossils inside.  I crushed a few small samples, which did reveal more microfossils.  Mostly what I could identify are broken bits of bones, but I'm sure there is much more that I'm missing. 


There is one object I found very interesting and beautiful, however I don't know what it is.  I would like to know what you think the first object might be.  That object is still attached to the matrix.  The other object I found in the same sample.  Both were revealed after breaking the sample.  


The first item is about 1/8th inch long but very narrow, and from some angles appears to be a hollow tube.   




The next object appears to be bone and is only about 2.5 mm wide and long.

The banding makes me thing mollusks shell. Would need to see more angles but the limited depth-of-field makes images difficult to see. Photographing tiny objects is a constant challenge. If you have the ability to vary the focal point of your photos you may wish to check into focus-stacking software to combine multiple images into a single image with a greater depth of field. There are several makers of software you can buy and several freeware versions.

Adding to the difficulty is the fact that I haven't attempted to remove it from the matrix yet, which limits the angles.  I haven't yet tried the vinegar, as I was hoping to get a handle on which rocks might be worth dissolving.  I'm sure some are much better than others, but at this point, I don't have enough knowledge to evaluate.  


Will look into image stacking software.    Thanks.
