Shane Rhader,

Thank you for contacting Mearto with your appraisal inquiry. My sincere apologies for the delay with the appraisal.

The presented object appears to be a fossils stone with several nit identifiable fossils. Mainly this is correct a Cambrian rock is filled with fossils perhaps if fossils are gastropods or Aldan with the measurements of 2 lb. 5.1"L x 4.2"W x 2.1". The fossils are probably Gastropods or Aldanella
Comparable objects were recently offered and sold on the international auction market. 
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 30 to 60USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards, 

George
