I'll visit Mungo Woman via her countryman Tas Walker's blog. Just briefly for her carbon dates:
What made the find significant was the assigned date. Carbon-14 dating (see Dating methods) on bone apatite (the hard bone material) yielded an age of 19,000 years and on collagen (soft tissue) gave 24,700 years.3 This excited the archaeologists, because that date made their find the oldest human burial in Australia.
But carbon-14 dating on nearby charcoal produced an ‘age’ up to 26,500 years. This meant that the skeleton, buried slightly lower than the charcoal, must have been older.

Which is down ...
How do I read this?
Carbon would be quicker replaced in collagen than in bone apatite? Or carbon 14 made a dip?
Either way, the human body has less lag backwards than a reasonably old tree, since all the layers of the tree get a mean date, only the newest incorporating this year's carbon.
So, if carbon 14 was overall on the rise, it makes sense that the tree material would look quite a bit older than the human material.
Or if the tree material in the charcoal was overall younger, it makes sense that the momentary dip continued, if that is why collagen seems older than bone apatite.
However, this is only about carbon 14, I consider the other methods even less trustworthy in this one, and for a recent find of Homo erectus, I find Ka-Ar as indicating with trustworthy if not foolproof indication mainly that as it was from the whenabouts of a volcanic eruption, it could be from the Flood.
ON SEPTEMBER 15, 1931, AT a distinctive bend in Java’s Solo River known as Ngandong, the top of an ancient skull came out of the ground. At the time, it was thought to have belonged to a prehistoric tiger. On further inspection, the skull, alongside more than a dozen pieces, was identified as having belonged to Homo erectus—the “upright human,” the archaic hominin that ranged across Africa, Europe, and Asia for hundreds of thousands of years. ...
The new paper dates the fossils to about 108,000 years ago—very recent for a species thought to have evolved around two million years ago.
Found: The Last Stand of a Human Ancestor

Let's be clear that 108,000 years BP is too old for carbon dating.
This date is too large and beyond the limits of present accuracy (55000 to 60000 years)

This means, 108,000 years BP is obtained by some other method.
And when I guessed Ka-Ar, I seem to have been off.
Nature : Last appearance of Homo erectus at Ngandong, Java, 117,000–108,000 years ago

Here, to resolve the age of the Ngandong evidence, we use Bayesian modelling of 52 radiometric age estimates to establish—to our knowledge—the first robust chronology at regional, valley and local scales. We used uranium-series dating of speleothems to constrain regional landscape evolution; luminescence, 40argon/39argon (40Ar/39Ar) and uranium-series dating to constrain the sequence of terrace evolution; and applied uranium-series and uranium series–electron-spin resonance (US–ESR) dating to non-human fossils to directly date our re-excavation of Ngandong5,15.
... Non-human fossils recovered during the re-excavation of Ngandong date to between 109 and 106 ka (uranium-series minimum)16 and 134 and 118 ka (US–ESR), with modelled ages of 117 to 108 thousand years (kyr) for the H. erectus bone bed, which accumulated during flood conditions3,17.
As I have not purchased either general access or the article, I can give no info on footnotes, but while Ka-Ar was a wrong guess, there is another indicator:
the H. erectus bone bed, which accumulated during flood conditions
In other words, it would seem the 14 Homo erectus fossils (see quote in the Atlas Obscura article) were pre-Flood men who were washed into a bone bed by - Noah's Flood.

Spoleto Martyrs, including
Bishop Sabinus of Assisi
Spoleti item natalis sanctorum Martyrum Sabini, Assisiensis Episcopi, atque Exsuperantii et Marcelli Diaconorum, ac Venustiani Praesidis cum uxore et filiis, sub Maximiano Imperatore. Ex ipsis Marcellus et Exsuperantius, primum equuleo suspensi, deinde fustibus graviter mactati, postremnm, abrasi ungulis et laterum exustione assati, martyrium compleverunt; Venustianus autem non multo post, simul cum uxore et filiis, est gladio necatus; sanctus vero Sabinus, post detruncationem manuum et diutinam carceris macerationem, ad mortem usque caesus est. Horum martyrium, licet diverso exstiterit tempore, una tamen die recolitur.
