help identifying flint with quartz? lometa TX

I was exploring some property of a friend in Lometa tx, outside of Lampasas Tx. (famous for celestite, calcite).I found amungst a large out cropping of what i believe is flint (some native american artifacts have been found in the area of this bed). It is blue, blue/grey in colour and is impregnated with several fossiles which in turn are filled with crystals. oh and this was on a high ridge overlooking the river valley, on a higher level i found lots of great limestone with many fossiles and quartz crystals.

My question is are these flint? if so any is there a specific name?

Rock a. was found in a different spot on the same ridge it too has the blue colour it has severl differend crystal structures, and severl nodules.

Rock b. found with the rest of the rocks, it has round formations across it, that range from blue to light grey.

rock c. found with rock b and d this one has a very distictive formation i cant tell if it is a fossile or mineral formation.

rock d. more from the same location, with distinctive fossiles

rock e. large rock with a great fossile

rock f nice crystal formations
