The bottom one is a sand/calcite concretion. They are found around a lot of desert lake areas ie: Salton Sea, CA and Pyramid Lake, Nevada. Basically just sand particles turned into cement by the addition of calcite. They occur as balls, scepters, dumbells etc. Some even form calcite crystal clumps with included sand......Mel

Thank you, Mel. Was wondering about that since it does appear to be of a sandy nature, sort of concretish.

Barite rose or gypsum rose. The other is a sand concretion of some type. Mel sounds like he knows what he's talking about (but then he usually does)
