The objects do not appear to be dinosaur eggs. They exhibit a distinctive concentric structure which suggests they were formed by deposition from water. In some you can see a distinct central straw-like structure, which is also interesting and uncharacteristic of fossil dinosaur eggs – as of course is the fact that they appear to be rounded only at one end. The structure of the laminae looks rather porous – almost like tufa.

What this suggests is that these objects are a form of “flowstone” – a calcium carbonate deposit formed by the flow of water highly charged in calcium carbonate. In other words I think they are probably stalagmite – though whether they formed on the roof or on the floor of a cavern remains uncertain. The straw suggests a roof (thin stalactites are often hollow centrally) but their mature rounded shape is more typical of something formed on the cavern floor.
