With all of this bitter cold weather here in Eastern NC the last couple of days, I have spent the time indoors searching some matrix from the Paleocene Aquia Formation, Piscataway member Charles County Maryland. Also cataloging and photographing my finds. I thought I would share some of the photo's here. I have tried to ID the teeth as best as possible, if anyone has any other thoughts on these please feel free to post them. Anomotodon novus .... Unknown, possibly Scyliorhinus sp. or Abdounia sp. ...... Brachycarcharias lerichei .... Cretalamna appendiculata ... D

Hi All, Does anyone here have a clue where I can get some lbs/kg's of matrix from the phosphate mines? I'm interested in the micro's that come out of it... but I can't seem to find a source/supplier for the stuff... Anyone?

I found this tooth in the Danian of the Paleocene. I have access to a microscope that is hooked up to a tv. My pictures are taken of the image on the screen so the images aren't great. I didn't actually measure the tooth, but it is approx. 2mm across and 3-4mm tall.

This tooth is too small for my photographic abilities so I know y'all will only be able to guess. This tooth was found in early Paleocene deposits. It is peg-shaped (cylindrical) when viewed from the side. It very round in the occlusal view. The base appears hollow. It is approximately 1mm across and 2-3mm from top to base. Any suggestions would be appreciated.

My wife found our largest Otodus tooth last weekend -- a lot of enamel missing, but otherwise fairly nice -- just over 1.5" slant height. I picked up whatever that is on the left. We would love to ID it... I can provide more photos if necessary, including edge-on shots. Thanks for looking!

Made a quick trip out to the paleocene of Maryland yesterday morning. HIghlights were some busted up ray plates and a paraorthacodus missing a couple of cusps.

a book review of: The Beginning of the Age of Mammals by Kenneth D. Rose. Johns Hopkins. 2006. $160 retail hardcover. Today, when we think of prehistoric mammals, images of mammoths, wooly rhinos, and Smilodon might come quickly to mind but they date back only to the recent ice ages - mere moments ago in geologic time. If your first thought was of Oligocene oreodonts, entelodonts, or hyaenodonts, then you might have a better idea of how many entire families of mammals had already diverged and died out even before the Oligocene Epoch started 34 million years ago.

The April issue of Geology (Geological Society of America) has an open-access forum with papers that discuss the dating of "Paleocene" dinosaurs. The papers are: Ludwig, K.

Found these sections of ramous coral in Paleocene upper Aquia Fm, Maryland. My ID is Haimesiastraea conferta Vaughan. I read that this species is common farther south, in Alabama, but rare or uncommon in Maryland. Rough pics attached. Is the ID correct? Thanks.

ID help needed. I found this well-preserved, ornate, large oyster in Maryland's Paleocene Aquia Formation. Is this the common Ostrea compressirostra? The lower valve's outer surface is quite ornamented, with radial folding along the protruding thin edges of the concentric growth rings (see pics). The valve margins are slightly discordant. The adductor muscle scar impressions, on both valves, contains what appears to be a thin layer of non-calcareous fossilized tissue. Specimen dimensions: Weight: 36 ounces Lower valve: height 6.75 inches, length 6.75 inches, convexity 1.5 inches Upper
