Globidens aegyptiacus (2) - deadly wrinkles

Post by Bruce Williams »

Hi folks,

Check my earlier posting in the Macro/Close-up forum to see what this object actually looks like and to find out more about its owner.

This is a close up on the ornate corrugation on the surface of the tooth. It is generally believed that these wrinkles helped improve the grip on its heavily armoured prey. The white/cream coloured material is what remains of the original rock matrix after (incomplete) preparation of the specimen.

The image measures approx. 5.5mm X 4mm.



Note: This was a really tough one to reduce below the forum standard of 200Kb as the original 800X600 was 510Kb ex Photoshop. I used XAT to remove all EXIF data and selectively paint in the areas of high and low JPG compaction.

Some interesting stuff here Bruce both this post and the other in macro with the link(s). I guess this reenforces the fact that at one time in history, water dominated the planet much more than it does now. Which reminds me of another tidbit of information I read somewhere and that is that 2/3 rds. of the earths surface is covered in water but less than 1% is freshwater and only a very small fraction of that 1% is drinkable. Considering the world population, it's a wonder we are not all dying of thirst. :-k

Good post Bruce. :D

Wonderful closeup Bruce. I`m thinking they had a grip like if you had 32 teeth made out of rough rocks. Would hold on to anything. :wink:

Nice shot, Bruce. Very abstract.

Bruce... always fun to see the "invisible" details a microscope brings to objects, and thus a better appreciation of how efficient and specialized these "parts" are.
