do we see evidence of Cretaceous life?

One specimen I found amongst unconsolidated Cretaceous sand, pebbles, and boulders appears to me to be a fossil nut. But please understand: I do not know that it is a nut.

You must try to help. Look in books, magazines, and on the web for information about any similar specimens. I will write to geologists who are expert in identifying fossil organic specimens. The following seven images were obtained by means of an Intel camera attached to a PCI card in a Windows 95 based machine. Keep in mind that the object is 4.5 cm long and 3.0 cm wide.

The following three images were obtained with an Intel microscope attached to a USB port on a Windows XP based machine. The magnifications are 10X, 60X, and 200X.

When looking at the specimen casually I had not noticed fibers nor capillary details. I returned to the specimen with a 10X handlens. In an attempt to show you what I consider to be interesting details, I used the Intel microscope again.

It is frustrating not to be able to show you an example as clearly as I can see it. Lighting is a major factor. Depth of field can be superior when using a handlens. But you can see fibers in the 10X microscope image on the right.

I think the "fossil nut" should be studied by a graduate student, under the guidance of an advisor who is experienced with studies on similar specimens.
