1. Roadside sediment was collected and filtered
to remove material from .2 to 1 mm in size.
2. The material was soaked several times in 10%
acetic acid.
3. Residues were then boiled in dishwashing soap
to remove clay and clean the specimens.
4. The resulting material was filtered and washed
again, then mixed with sodium metatungstate at a specific gravity of about
2.8 -- to float off lighter materials, removing about 50% of the sample
This unstudied sample contains about 6 conodonts per gram, mostly large specimens, as well as a large amount of other biological materials representing microfauna in the shallow sea estimated at less than 30 meters in depth. Species of conodonts may include Plectodina and Ozarkodina and other unidentified specimens. Have fun! -- JD
