This past weekend was the 50th annual Rutgers Geology Museum open house, which was an excellent opportunity to attend guest lectures by professionals and also a chance see the museum's collection. The event was very well attended, and in between lectures (the lecture by Dr. Isaiah Nengo on his work with Nyanzapithecus alesi was excellent) seeing the museum was a hurried, crowded affair. The museum building is a tall 19th century structure with many large tall windows, so on this sunny Saturday sun glare on the glass cases was unfortunately a real and unavoidable problem. Nevertheless, I made an effort to get some photos of the museum to share with TFF. The Mastodon is a Salem County NJ find. Particularly exciting for me as a huge fan of Phytosaurs was seeing their specimen of Rutiodon manhattenensis, which despite its specific name was found on the New Jersey side of the Hudson. Yet another example of New York stealing New Jersey's credit! Hidden in a corner (it was packed in there, things crammed into corners to make room for tables) was a skull of Mosasaurus "maxmimus" which I'd have loved to known more about since it was apparently a New Jersey find. Alas, no more info than that. Next to it was a cast of the original find Mosasaurus hoffmanii from the Netherlands, which was neat to see in real scale.

The reverse of this piece has specimens of Tetragraptus serra. and this side shows fragments of other graptolites, possibly Tetragraptus and / or other Dichograptids.

One of a number of spiral monograptids from this period and a zone species, these have all been referred to Monograptus at various times as well as separate genera based on rhabdosome form which may not be of significant importance. It is bisected by an unidentified straight Monograptus. Reference for ID (as Monograptus spiralis): Elles & Wood 1901-1918, Monograph on British Graptolites, Pal. Soc. Monograph 33. (Plate XLVIII, fig. 7). Now generally referred to Oktavites Levina, 1928, e.g. in J. A. Zalasiewicz, L. Taylor et al 2009, Graptolites in British Stratigraphy, Geol Mag. 146, pp. 785-850.

A common scandent, biserial form, frequently found alongside the zonal species Didymograptus murchisoni at this famous locality. The individuals on this surface are current aligned. Reference for ID: Elles & Wood 1901-1918, Monograph on British Graptolites, Pal. Soc. Monograph v.33. (Plate XXX, fig 6)

From the album: Various
Didymograptus marchioness graptolite from Abereiddi Bay, Wales, U.K. Ordovician. -
I found these fossils in Northern Pakistan in the Murree Hills. The fossil is a bit small, I included the hand for scale. Other fossil found in the vicinity were marine fossils such as shark teeth and bivalves. I am guessing they are graptolites, but I do not really know. I am guessing the two fossils are of the same species, although they might be two different species (they were from two different but near locations)

The following graptolites were collected at two Luster’s Gate locations east of Blacksburg, Virginia, one on VA 723 (UTM 17S 556351.49 4121426.16) and the other on VA 785 (most likely, UTM 17S 556851.28 4122155.54). I remember the second location as being just north of a sharp bend in the road and I wish Google Earth would run a street view down VA 785 so I could verify it. The locality on VA 785 has been listed as having exceptional preservation (lagerstatten) but I had never considered it so, until I found Specimen # 6. Anyways, I’ve photographed and scanned six specimens and I am having problems pinning down any type of assured ID other than graptolithina. I’m not well versed in graptolite taxonomy and I realize the preservation is somewhat poor, so I would expect speciation unlikely. But, maybe someone in the FF familiar with the taxa and/or the site can verify my lame attempt at taxanomic placement of some of the specimens and make a generic or family/group determination on all. That would be most helpful. Also, is anyone aware of where I might obtain a copy of the following thesis/dissertation other than the VPI library? J. Duval Shultz, 1919. The Graptolites of the Luster's Gate Locality, Montgomery County. Virginia Polytechnic Institute, 18p. Specimen#1 Specimen #2

Hello, Here Graptolites I found last week in Scania, Sweden. I am sure only about the period: Middle Ordovician, just before the limit with the upper Ordovician. Can someone help me with the genus? Thanks in advance D the single specimen measure 6 cm

Just felt like sharing this fossil - Didymograptus Murchisoni Location: Abereiddy Bay, Dyfed, South Wales. Age: 475 myo, Ordovician Thanks for looking! Best wishes, Thomas.
