Are they floss picks, or are they perhaps plastic figurines of extremely long-necked herbivorous dinosaurs from a cereal packet, with the tail snapped off, and a thread between the legs to stabilise them and slot into a folded cardboard stand?

That's my theory.

Maybe a cereal truck jack-knifed, scattering its load across the whole neighbourhood, and all the biodegradable contents have rotted away, leaving only the dinosaur fossils.

Take care of yourself, Bev. I know you have a great many people who have been delighted and moved by your words and who are wishing you all possible fortitude, fortune and forbearance.
