Hi all! New to the forum. Here is a nice scolecodont that I collected last year. What is preserved is the mouth parts of an annelid worm. It is from the Ordovician of Kentucky.

Hey guys, thanks for the welcome.

(Beware of the hungry Telost!)

Probably, during the Ord it was the agnathids, and nautilids, that were of primary concern for the annelids. Though, around here, agnathids are unknown.

This is for Jimbob, and anyone else.

Dear fallow Texan;

  Hi there Jimbob. I would be very happy if you would go new theories and look at Freemason’s science.
Even though it is not a new theory, but a study of the freemason’s work on the US dollar bill. It is a copy of what was on the old  Temples of Seth, Enoch, Solomon, and Hercules six thousand years ago. And it shows the makeup of the Earth, well before there was any Witten word.

G-man;

Just saw this nice photograph of Halema`uma`u's plume rising straight up in the absence of low altitude winds (the moon is visible as a little bright speck just above the small dark cloud, to the right of the plume).



(Photograph by M. Poland November 13, 2008)

The photograph is one of the featured pictures on the USGS HVO website at:

This is a lava bomb from a shield volcano in southern Australia. This specimen is from my own collection.

Some of the columns seem to be clearly separated from the ones beside them i.e. there seems to be a clear gap between some of them - is this so?

I agree.  Keep in mind the columns shown in the photo have been exposed to elements and undoubtedly weathered.  Basalt columns form as the lava cools and shrinks- the most efficient cooling shape being hexagonal.  A few more photos from Giant's Causeway:



not sure which is better looking- these unique rocks or my daughter?

Basalt columns at the "Pipe Organ".  It's easy to see how these could erode down to the "steps" seen at tidewater.

That was a great link, Jim.  The Precambrian tillite, was specially interesting.  The picture was apparently taken by Jon Landvik, but one has to wonder if it was really John Wayne.  :)
