Following on from the Bullyland trilobite ID discussion, can anybody put a name to the other Bullyland invert figures?  |

REPOST of my potential ID for the trilobite:  OK - presuming I am looking at the right toy - Hollardops mesocristata? If not, then I think it's probably a closely related species. It's a common commercial species so the sculptor would have had easy access to a specimen for inspiration and guidence. This is the toy I'm going by -  |

The best I have been able to come up with for the medusa is Qudrimedusina quadrata; as far as I can find, it is a European Jurassic species of jellyfish.
And I like the Hollardops ID. As for species--who can tell? We have PVC replicas based on sculptures that were probably based on pictures.

Nice find about the trilobite. As for the jellyfish, I found a common modern species that is very simmilar to the toy, the Aurelia Aurita, but I don't know if that lived in the Jurassic  . I'm assuming that the specimen is German (classic Bullyland chauvinism ;D) and was found in the Solnhofen limestone, maybe that could help. Then again, it is almost impossible to identify clearly most of the jellyfish fossils due to the softness of the body  |

Today i just bought the VCD WWD Sea Monsters( A WWD Trilogy ) very interesting it show what your picture had. Check that out man REPOST of my potential ID for the trilobite: OK - presuming I am looking at the right toy - Hollardops mesocristata? If not, then I think it's probably a closely related species.

You mean, this very species of Trilobite is featured in the program?

Given the size of the trilobite he lifts, I doubt it was this one (they are apparently in the 5 cm range). The one he picks up is more reminiscent of Isotelus], or something similar (I don't recall it having the fringed margins on the sides, for example, or a tapering pygidium); the one he lifts is over a foot long.

I just read in Wikipedia that it is indeed an Isotelus. |

If i'm not wrong it did but just showing abit of it. i bought the VCD at S$10 = US$4.90 cheap right You mean, this very species of Trilobite is featured in the program? |

Oic i never know that , anyway is not my cup of tea  If i'm not wrong it did but just showing abit of it. i bought the VCD at S$10 = US$4.90 cheap right Again, as Tomhet and I have pointed out, it was Isotelus, not Hollardops |

Hey guys!!! I think this could be it, Greenops widderensis:  |

Hey guys!!! I think this could be it, Greenops widderensis: The genal spines are way too long. I think Hollardops is a better fit. And though I'm no expert, I'm guessing that the two are very closely related. |

You're right about the genal spines being a little too long, but Hollardops is just as problematic, look at these images:  and  and  As for the jellyfish, I don't think it's a Quadrimedusina; granted, the four gonads are there, it is from the Solnhofen Lagerstätte, but the bell seems too round, unlike Quadrimedusina:  All along we've thought that the Bullyland toy was a member of the Scyphozoa class, (i.e. true jellyfish) but what if it is from the Hydrozoa class in the medusa stage? Today I found a very good candidate in the Treatise of Invertebrate Paleontology, the Hydrocraspedota mayri, also found in Germany. In the fossil one can clearly see four gonads too and the bell seems round enough. The only problem is, I don't know if it had tentacles as big and thick as the Bullyland toy's |

The only problem is, I don't know if it had tentacles as big and thick as the Bullyland toy's I don't know about the Hollardops; the pictures put up earlier had much shorter spines; the variation is probably intrageneric (how many species are there, anyway?). As for the jellyfsih, the hydrozoan looks like a good fit; they only refer to it as a Medusa, so it could be from either group. As for the tentacles, I have no idea what a hydrozoan tentacle structure is. |

I know it will be a pain in the behind to put a name on the ammonites  |

Post by Dinotoyforum on Apr 18, 2008 17:47:17 GMT
Too right! Here is my guess for the small ammonite -  =  Kosmoceras spinosum ...Perhaps |

Post by Dinotoyforum on Apr 18, 2008 17:56:51 GMT
Actually no - The Bullyland version doesn't have nobbly bits on the keel...we are looking for an ammonite like K. spinosum in side view, but with a smooth rounded keel...

Although I have never been much for Invert IDs, I have always thought of the "small" ammonite as Perisphinctes (a species without the processes at the aperature); and the large one as something along the lines of Pachydiscus.
But those are wide open to re-interpretation
