For more than 10 years that I have been going through this forum, I always see so many photos of identification requests with a coin, a x-dollar bill or any useless object to measure the size of the fossils.
Quite often, other members and I ask to have a real ruler in cm or inches on the photos, or to have the size of fossils in the text, some say that they do not have a ruler... How can we not have a rule at home when we tinker, when we have a schoolboy at home, when we knit or sew? Moreover, it is not expensive and there are rules in every department store. We can also find rules drawings on the internet and print when we have nothing else.
So in the face of this recurrence that poses many problems for those who are willing to do a service to identify your fossils, I made a millimetre paper on my computer this morning. It just took me 1/4 hour.
All you have to do is print it on a thick sheet of paper and place your fossils on it before photographing them.
Now no one can say that he has nothing to measure his fossils.
Your turn !
