Posts treating: "fragment"
Sunday, 01 May 2016
One one of my regular trips up to Arkona, Canada I found this small scrap of fossil and hung onto to it as it reminded me of something. Well that something turns out to be a piece of a Bryozoan called Ptilopora striata (sometimes spelled Ptylipora). This bryozoan is typified by a single, strong, central "mast" with branches angling off at 45 degrees along the length. The individual branches sometimes have cross supports with neighboring branches as well. Overall the fossil has a herringbone [...]
These little bryozoan "chips"were interesting to find and I'm trying to figure out what genera they are. They bear a resemblance to Paleschara sp. but they are not encrusting a shell, which is how I find them most often. they could also be another genera called Leioclesma sp. which looks similar but does not have the encrusting habit. Both of the below specimens did start out colonizing a small hard surface with the first specimen growing over an ossicle from a crinoid stem.Specimen #1 - Dorsal [...]
“I wanna know what love is, I want you to show me, I wanna feel what love is, I know you can show me”. For fans of slow rock music of all time, probably remember the lyrics above fragment which is part chorus of a song kunci gitar slank legendary world. The song is one […]

Recently, I got a rare opportunity hunt for fossils in the Waldron Shale and a number of fossils were found. Nothing earth shattering but it was fun to get out after a long absence to poke around and see some familiar fossil friends.
This first image is of a fragment of a Trimerus trilobite pygidium. Not sure if it is all there in at least one lobe is and probably also the middle section

This picture is of a microfossil called a scolecondont (part of a worm jaw). It was found in the Waldron Shale of Clark County, Indiana, USA. The age is around 420 million years old which would place it in the Silurian Period.It reminds me of a Silurian scolecodont found in Sweden called Kettnerites sp. Also one found in New York called Nereidavus invisibilis. I have not been able to find much research on the ones found in the American Waldron Shale though.Thanks to Kenny for the
If you’re just joining us, this post is a follow-up to this one, in which I considered the possible size and identity of the Recapture Creek femur fragment, which “Dinosaur Jim” Jensen (1987: page 604) said was “the largest bone I have ever seen”. True to his word, Brooks Britt at BYU got back to
From the electronic version of the New York Times,February 15, 2013.Reports from Russia today tell of hundreds of people hurt during the passage of a meteor. By coincidence or not, this has happened on the very day that a known asteroid, 2012 DA14, is to pass within 17,000 miles of the earth, a widely-publicized happening for which the public has been reassured that there is no danger of the asteroid actually hitting the earth! It will be interesting to follow the speculations: Was this [...]
I have been studying some more of the material from the island of Guam. The first picture shows a Baculogysina foraminifera shell be tested it a weak acid (white vinegar). It looks to be a carbonate.The next picture appears to be an Amphisorus foraminifera. The following image of a foraminifera appears to be Calcarina.The last image is of maybe a fragment of an Amphisorus.Images have a 2-3 mm field of view.Thanks to Pam for obtaining the specimens and Herb for getting it to
I happened to be browsing Gerald L. Woods superb Guinness Book of Animal Facts and Feats (3rd edition) this morning, and happened across this fragment on page 76: Not surprisingly, hummingbirds have the highest energy output per unit of weight of any living warm-blooded animal. The wording struck me as strange: highest of any living warm-blooded
Not sure what this is, thought it might be some sort of crinoid calyx but cannot find where the stem attached. Reminds me of a brownish dinner roll or slightly deflated doughnut hole. It is about 2 cm wide and 1 cm tall embedded in matrix with a lot of Cryptolithus trilobite pieces. The brown material might be argonite. Matrix is the Kope Formation of the Ordovician period found in Carroll County, Kentucky.Also included is a picture of a fragment of an Ambonychia clam [...]
On January 15, 2011, I posted some pictures of a fossil I thought was some sort of Silurian clam. The shell was asymmetric which led me to believe it was not a brachiopod. After studying more of the work of two researchers at the New York State Museum, Charles E. Beecher and John M. Clarke I now believe it could be the Atrypina disparilis brachiopod. Fossil was found in the Waldron Shale of Clark County, Indiana.They originally called it Coelospira disparilis Hall 1852 but [...]
Having already talked about naming fragments a great many moons ago, it seemed about time I wrote a little more on this subject. Fossil archosaurs of course can be represented by complete articulated skeletons down to just parts of single bones or isolated teeth. As I have discussed before, obviously not of these are equally
Paleontologists have not found much of Oxalaia quilombensis. A fragment of the snout and a portion of the upper jaw are all that is known of this dinosaur. Even so, those two parts are enough to know that Oxalaia was one of the peculiar predatory dinosaurs known as spinosaurs, and a giant one at that.

Abstract - Oxalaia quilombensis (Kellner et al. 2011) is a new large spinosaurine from the Cenomanian of Brazil based on a fused premaxillae and a fragment of maxilla. It differs from the other known spinosaurine snouts in the shape of the rosette, the presence of ventrolateral rugosities and the presence of two replacement teeth in
Of all the organisms scientists have found in the fossil record, Tyrannosaurus rex is the most prominent ambassador for paleontology. No dinosaur hall is complete without at least some fragment of the tyrant dinosaur, and almost anything about the dinosaur is sure to get press coverage. We simply can’t get enough of old T. rex.
The magnitude 6.3 earthquake that hit the last February 22 New Zealand not only caused havoc in city of Christchurch but also affected the Tasman Glacier, nearly 200 kilometres to the west of Christchurch.Ice with the overall mass of 30 million tons broke off from the glacier tongue, a fragment nearly 1.200 meters long and 75 meters broad. Eyewitnesses report that the break-off caused a three meter high wave. The glacier tongue was already instable and closed for tourists due to heavy rain in [...]
Stidham (1998) described the above fossil, a fragment of fused dentaries, from a find in the Hell Creek Formation of Wyoming, USA, as a potential morphologically modern psittaciform mandible. This jaw is remarkably parrot-like: Stidham was relatively careful in his description, positively comparing the material to lorries, which unlike the parrot above, have a much
Over Thanksgiving break in 2009, while scouting out a locality for a future permit application, I spotted a nice braincase of a small odontocete skull exposed in a cliff face. The following november, I received a permit, and returned to the locality one year later with my friend Chris Pirrone to excavate the fossil. I knew this excavation would be slightly challenging, because we would be pedestaling the fossil sideways instead of from the top (I have done worse before - I have successfully [...]
