It certainly has that appearance and, if so, horizontal 'cuts' might be axe marks. |

(2010-02-10) | Hang on a minute, trees were fossilised millions of years ago - who made the supposed axe marks? | dowser
(2010-02-10) | Fossilized tree? I think that experienced petrologist could answer it at once.... | Thingy
(2010-02-10) | I hasten to add that it's not my suggestion! See the forum topic 'stone or tree' | cerrig
(2010-02-10) | The stone behind the pillar has a similar bark like texture in this photo. Is this a true similarity,or a trick of the lighting,as can happen.?
Incidentally Andy,there is a petrified forest just off the West Wales coast,periodically uncovered by very low tides. These trees are thousands,not millions of years old. Certainly within the time of human habitation of this area. So this pillar could be wood turned to stone, but how to tell for sure? | davidmorgan
(2010-02-10) | I guess you could look a the top and see if there are any rings. | pab
(2010-02-10) | Cerrig mentions the forest in West Wales - there may be others, but certainly there is one at Amroth where the trees are visible at low tide. These are said to be 7000 years old, drowned when sea level rose, but I thought of them as petrified rather than fossilised? I do love davidmorgan's suggestion of checking for rings though! | Thingy
(2010-02-11) | The simple solutions are always the best! I wonder if there will be a frantic rush to Bryn Celli Ddu, researchers fighting and squeezing down the passage to be the first, with mirror and torch, to find the tree rings and so end the great mystery. Note to self: 'when next visiting BCD, take mirror & torch.' | Thingy
(2010-02-11) | Cerrig has a good point. Petrified trees are well known in many places and date from the time of human habitation. I'm no expert, but my understanding is that there is a difference between petrification and fossilisation, though the object appears the same. |
