I am Jens Kosch, now in the ...Hi Nima, great work! <br />I am Jens Kosch, now in the Zanno lab at Raleigh, NC, but previously I was at FU-Berlin and I wrote my Masters Thesis on the dentigerous bones and the dentition of Giraffatitan. <br />But I don't like the fact that you ignore the currently valid collection numbers for the MfN specimens. You simply use Janensch's designations.<br />All the collection numbers are HMN are now MB and for the fossil non avian dinosaurs it is MB.R. (the Museum für Naturkund has no further connections to the Humbolt University anymore. Also see: https://dinosaurpalaeo.wordpress.com/2011/12/03/the-mfn-berlin-1-introduction/).<br />The specific collection numbers are: <br />- MB.R.2180 (SI of Janensch and other sources (e.g. Taylor 2009, Paul 1988), the head is also called S 66 in Janensch 1935-36). This one has the following cranial bones preserved: Parietal (sin + dext), frontal (sin + dext), nasal (dext), lacrimal (dext., sin partial), squamosal (dext), pterygoid (sin), ectopterygoid (sin), palatine (dext, sin partial), premaxilla (sin), maxilla (dext, sin), dentary (dext, sin), angular (sin), surangular (dext, sin, both partial), splenial (sin), coronoid (dext), occipital condyle, basioccipital, basisphenoid and parasphenoid, exoccipital (dext, sin), supraocciital (partial), prootic (dext, sin), orbitosphenoid (dext, sin), laterosphenoid (dext, sin), quadrate (dext, sin partial), <br /> <br />- MB.R.2181 (SII of Jannensch and other sources, the head is also called S116 in Janensch 1935-36). This one has the following dermatocranial bones preserved:<br />Prefrontal (dext), postorbital (dext, sin partial), postfrontal (dext, sin partial), jungal (dext), squamosal (dext partial), quadratojungal (dext, sin?), pterygoid (dext, sin), ectopterygoid (dext, sin), palatine (dext sin, both partial, just lateral parts), premaxilla (dext, sin), maxilla (dext, sin), dentary (dext, sin), angular (dext, sin partial), surangular (dext, sin), splenial (dext, sin), coronoid (dext, sin), prearticular (dext, sin), quadrate (sin), articular (dext, sin), ca. 20 plates of the scleral ring<br /><br />- MB.R.2223 (skull t1 of Janensch)<br /><br />Large portions of the right maxilla MB.R.2181.3 were heavily reconstructed with plaster. It is kept as a single unit by three metal rods and connected to the premaxillae MB.R.2181.1-2 by three other metal rods.<br /><br />Isolated tooth rows (“dentures”) are known from both individuals (MB.R.2180 and MB.R.2181) and a few others<br />- MB.R.2181.23.9 (functional teeth of left maxilla)<br />- MB.R.2180.20.12 (functional teeth 1-6 of left maxilla and functional teeth 4-8 of left dentary)<br />- MB.R.2180.21.7 (functional teeth, likely dentary dext 1-2 and dentary sin 1-3<br />- MB.R.2182 (functional teeth, likely maxilla sin 3-7)<br /><br />- MB.R.2390 (=WJ4170, also mentioned as WJ 1111 on page 154 of Janensch 1935-36)<br />This is a “denture”, purely isolated teeth in syn vivo arrangement, not a bone!<br />From the same site also comes a single prefrontal. <br /><br />Other cranial material includes:<br />- a single frontal from the site St (current collection number unknown t me)<br />- Y-1 (current collection number unknown to me):<br /> occipital condyle, basioccipital, basisphenoid (partial), exoccipital (dext, sin), supraoccipital, prooticum (dext, sin), orbitosphenoid (sin partial), laterosphenoid (dext, sin, both partial)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6861762923957413794.post-70713807744184422002016-07-14T21:32:04.192-07:002016-07-14T21:32:04.192-07:00Thanks, that is good :) Would be nice if the DML d...Thanks, that is good :) Would be nice if the DML discussed some of my ideas after this.
