But Virgo would have been around the spring solstice back then because of precession.
Perhaps even more astonishingly, the ancient engravings seem to illustrate the changing positions of constellations in the sky, indicating an appreciation of the concept of precession 10,000 years before it was first documented by the Ancient Greek astronomer Hipparchus.
Yet the study’s most striking find relates to a separate pillar, which appears to illustrate the Taurid meteor stream moving through the constellations Aquarius and Pisces over a period of several weeks.
No. The Taurid meteor shower is called that because when the orbit of the meteoroids (mostly dust) intersects with Earth's orbit they appear to be coming from Taurus. The direction of Earth's axis does not change that. It would just change the season they arrive in and how high in the sky Taurus is. Also, differences between then and now would not show an appreciation of the concept of precession. It would just show what the observation was at the time. The knowledge of precession required hundreds of years of observation.
It looks like the author doesn't understand precession. Hopefully the original researchers did and it just got lost in the writing.

All these zig-zag marks and a round ball at the bottom look kinda like a comet depiction to me................
Kepler among us . NO/s. Who knew?
