Buddha's tooth, ashes, footprints and other marks There are many places that claim to have a part of the Buddha, a tooth, ashes, a footprint (sri pada) etc.

I would like to know, according to Theravada tradition (but I accept answers from other traditions), what is recognizable as being true? What is left on earth from the Buddha?
I found this information on Wikipedia. I hope you find it useful!

In January 1898, W.C. Peppe led a team of men to unearth a large mound on his land. Having cleared away scrub and jungle they set to work building a deep trench through the mound. Eventually they came to a large stone coffer which, on opening, contained five small vases containing ashes and jewels .[6]
On one of the vases was an inscription which was translated at the time to mean &quot;This relic deposit of the Lord Buddha is the share of this renowned Sakya brethren, his own sister’s children and his own son;&quot; meaning that this reliquary contained the ashes of the Buddha, also known as Siddhārtha Gautama[note 1], a member of the Sakyas [4] (however, there is no mention in the Buddhist scriptures of the Buddha having a sister). And in the 1970s the original interment site of the Buddha's ashes at Piprahwa was claimed to have been discovered by the Indian archaeologist S.M. Srivastava several feet deeper than the coffer containing the relics that W.C. Peppe had excavated.[5] This find was dated by Srivastava to the period in which Buddha lived.
