Stump puffball/pear-shaped puffball (Lycoperdon pyriform). https://mushroomexpert.com/lycoperdon_pyriforme.html

Stinkhorn ‘egg’ image. http://www.nigeldownerphotography.com/details.php?image_id=606&sessionid=a23940826d244819c00648c7bda9bdf7

It hard to tell from the image. I’m wondering if these could be something in fungi group perhaps? For now, check out these included links for wolf’s milk slime mold (Lycogala epidendrum), stump puffball (Lycoperdon pyriforme) & common stinkhorn. Again, this is not an ID, perhaps you can give us an up date whether these are fungi or eggs of reptiles, birds etc…Best wishes! wolf’s milk slime mold image. https://www.inaturalist.org/observations/13289052
