Hello everybody. I was a geologist in a previous life (Liverpool University 1999) and had never really found anything interesting. I was picking some oversized from a clay lining system we are deploying and came across this oddly shaped rock. On inspection it looked very glassy, almost like chert would inside. But the shape looks so much like a joint I wondered if it might be a fossil. The bulbous end is very pitted which reminds me of bone, but where it has broken it is very polished. The clay is (was) an alluvium deposit from Cardiff area (river Taff)
Hello I am a rookie again at 67yo.

These tubes range 3' and more, running in curves with off shoots and branches reminding me of corral. When I found these I was totally not prepared to collect or carry much so this is a broken off piece. Along wit
