Animals within stone

There are several documented cases where frogs, toads, and other small animals are found concealed within solid stone – alive. There are other instances too, where workers would cut down trees, and find hoards of frogs within the interior. Weirder still, people have found creatures within not just natural formations such as rocks and trees, but manmade establishments. 

In August 1975 construction workers in Fort Worth, Texas, were breaking up concrete that had been laid down more than a year before when they came across a living green turtle. The animal must have been caught in the concrete as it had been poured because the body-shaped hole in which it had stayed during that time was clearly visible.

Though reports of entombed animals have occurred as recently as the 1980s, scientists have paid little serious attention to the phenomenon since the nineteenth century. During the 1820s, English geologist William Buckland conducted an experiment to see how long a toad could remain alive while encased in stone. He placed toads of different sizes and ages into carved chambers within limestone and sandstone blocks, then buried the blocks in his garden. A year later, he dug up the blocks and found that most of the toads were dead and decayed. A few toads that had been in the limestone (which did contain small pores) were still living.
