  3. Bands in Marine Mammal teeth

    Very few mammal teeth will grow, mostly tusks. No. The enamel forms all at once.
  4. 400 Million years in 4 hours

    Nice to find 3 time periods in 10km range with such picturesque atmosphere. Fossil hunting at its finest.
  5. These are always my favorite clams and I still call them Edmondia or “Clam-Clam”. There is a vacant area near Reed Road that Walter and I would collect. This area had some barren patches several yards long and wide and every concretion contained at least one clam and many contained multiple clams. The area is still vacant, but because of the area being covered by grass nothing erodes out. Hopefully one day there will be some construction there and I will one again snatch these favorites up.
  6. Dinosaur skin impression or mummy skin

    I will do that. He send me one photo more... it seems that any photo costs 100$ hahahah
  7. Spinosaur jaw section?

    Awesome, thanks:) well, ITS not awesome, but the heads-up sure is:)
  8. White River Oligocene Prep - Leptictis

    looks really nice!
  9. French Mosasaur Teeth

    Et tu n'y perds pas au change : il vient d'un endroit méconnu pour ses oursins (et complètement inconnu de la majorité des Français). C'est donc un specimen très rare. And you won't lose out : it comes from a place little known for its urchins (and completly unknown by the majority of French people). Therefore, it's a very rare specimen.
  10. 400 Million years in 4 hours

    Thanks for the trip report Southern Germany is amazing for it's abundancy in different Sites and ages Have you tried cutting and polishing any of those favosites? Best Regards
  11. In the Journal of Vertebrate Paleontology, Vol. 7, No. 1, 19 March 1987, there is a note by Jiri Zidek concerning "...Syntax in Taxonomic Statements." There follows a response from Richard Estes. Zidek argues (among other things) that "cf." and "aff." are synomymous. Estes disagrees. Estes, the Editor of the JVP at the time, says the following: Lucas (1987) also discussed the usage of the qualifiers aff. and cf., stating that "most vertebrate paleontologists understand the meanings of aff. and cf." My discussion with vertebrate paleontologists, and also my reading of their manuscripts, suggests that this may not be the case. Zidek (1987) believed the two qualifiers to be interchangeable. If he is correct, one of them should probably be abandoned. I think that they often have, and should have, different meanings. If I have a fossil element that does not differ structurally from that of a particular species, and also does not display diagnostic character states of that species or genus, I may wish to indicate this similarity in a structural sense (there may be stratagraphic and geographic reasons for this as well). The use of cf. in this case indicates a conservative identification, i.e. simply "to be compared with." To me [Estes], the use of aff. indicates a greater degree of confidence. Perhaps I have a specimen that has most of the diagnostic character states of a taxon, or has one or two that differ very slightly, such that I have some minor doubts about referring it directly to that taxon. In this case I use aff. as an indication that I believe this specimen to be very close to the taxon concerned. Obviously, there is intergradation in these two concepts. and it is certain that different workers will not apply it in exactly the same way. But if there is an attempt to follow such usage consistently, I believe that the author's degree of confidence in the identification is more accurately represented. Because both [aff. and cf.] are an "alias for tentative identifications" (Zidek, 1987) information content may not be increased; again it is a matter of taste.
  12. Dinosaur skin impression or mummy skin

    Its very possible but without additional views I'm not willing to make that call. Purchase it under the condition that it can be returned for a full refund if you are not satisfied.
  13. Today
  14. Spinosaur jaw section?

    Looks like a Spinosaurid tooth composited into a Croc jaw.
  15. Struthiomimus Vertebrae

    I need a red smiley... Coco
  16. I think you are over thinking this. In your example if its similiar to Tyrannosaurid then "Tyrannosaurid indet" works. If its really unknown than "Theropod indet" is the proper designation. I use cf when a species is described in a different formation but not the one my specimen comes and they look identical...for example Troodon teeth from the Hell Creek Fm should be described as "cf Troodon formosus".
  17. Bone or stone?

    +1 for not bone
  18. My motto is - if you are not searching, you will not find. It is hard passion becouse ambers usually are checked by sellers. If they miss something - here i am
  19. Oxford Fossil Show

    Having exhibited there with Matt I found it pretty poor certainly compared to Bakewell. There are few affordable fossils and it’s mostly minerals. If it’s close to you pop along but if it’s a trek I wouldn’t bother.
  20. Thank you Don i really appreciate it Also thank you for kind words about photos my friends !!
  21. Painting epoxy putty

    Hi guys, I’m rebuilding some matrix on an ichthyosaur block I've recently acquired. What paint type do you use for colour matching? ta John
