FootnotesCarcharodon megalodon is regarded as one of the largest and most powerful marine predators in vertebrate history and likely had a profound impact on structuring of the marine communities. Fossil remains indicate that this giant shark reached a length of more than 16 metres (52 ft) and also affirm that it had a cosmopolitan distribution. Scientists suggest that in life it looked like a stockier version of the great white shark, Carcharodon carcharias.

The box contains an educational set of geometric shapes comprising 120 individual three-dimensional cardboard pieces with printed names and numbers corresponding to the key, arranged in various smaller interlocking configurations. The producer, Louis Dupin de la Guérinière, was a French civil engineer who began to produce and sell folded models to show the physical properties of polyhedrons. His models were intended not only as educational aids for students of mathematics, but also for those whose work involved perspective drawing, stone-cutting and mineralogy. The sets began production in the 1840s and were a popular study-aid. The present example has an adhesive label in the lid naming the supplier as Crosti of Rue Ste. Catherine, Bordeaux, France.
