  2. I didn't know where to put this news article. It really doesn't qualify as fossil news or as a non-fossil web site. However it is the type of insight that many TFF members would find interesting. So the member news is this member read this article. The Endowment Effect is a behavior where we over value something we already own. This is important in economics since it leads to mismatch between selling and buying prices. It makes fossil trades harder too. Not every class of items has the same degree of Endowment Effect though. These researchers found that items more important for our survival or attracting a mate had larger effects. This implicates evolutionary forces in this particular cognitive deficit. Other primates share this trait as well. https://phys.org/news/2020-05-endowment-effect-evolutionary-roots-cognitive.html
  3. I have finally managed to persuade a teacher to let me do an at least slightly paleontological essay so i'm really happy, however the topic i'm doing is quite broad but i do have 1.5k words to summarise it in, i would like briefly outline the key crossroads in the evolutionary lineage of humans, i have shortened these to: Sarcopterygii-tetrapods , reptile to mammal, 4 legged to 2 legged , i would appreciate any opinions on this and any literature that anyone knew would be helpful, thanks again, will
  4. Just watched fascinating documentary on equid evolution- bout half on the origin (Dawn horse), then progresses to present-day..........Bone
  5. I am new to collecting meg teeth so I hope my question is not “dumb.” Are the tooth cusps on a C. chubutensis vestigial structures from the earlier three pronged tooth like on O. obliquus? I read a physics article about how the megs tooth serration evolves from the smaller prong teeth getting sharks caught on larger prey causing them damage. Did the improved serration as the sharks evolved to be larger lead adult C. megladon adults not having cusps at all? I hope the question makes sense.
  6. I keep thinking I must just be stupidly forgetting/overlooking something, but I haven’t been able to come up with it in a long time. There were birds during the Mesozoic(hesperonis, for example), long before theropods evolved into birds(after the Mesozoic, right? I thought all the already very bird-like Dino’s, like archaeopteryx, dead-ended at the end of the Mesozoic)....what am I missing, here? I’ve been looking at bird evolutionary charts, and none of them seem to make sense of that. I’m not all that learned on this topic, but there are things I at least THOUGHT I knew about it, but I’m now very confused because of it, and questioning how much I really DID know! This is is just another thing that’s caught my eye, that seems strange. I’ve always thought this wasn’t the case, but as I’ve said, I’ve never known very much about this whole subject. According to the charts I’ve seen that specify this aspect, songbirds and most birds in fact, are more closely related to the first Dino/birds than raptors are(hawks/eagles/falcons). Are raptor really some of the furthest related to dinos(seemingly in the furthest 15-20%, or so)? Lastly, I’m having a very hard time finding information on terror bird evolution, and where THEY fall within the bird tree. Is anyone familiar with that?

  8. Hi! I made a small visit to the Natural History Museum in Maastricht today to visit the new small exhibition named "Whale: Locality Maastricht" which centers around some Eocene whale bones from an undescribed whale found in the ENCI quarry in Maastricht. The exhibition explores further into the evolution of whales, it's a small exhibition but worth a visit if you haven't seen the museum or if you are really interested in whale evolution. Should any of our Dutch, Belgian & German members decide to visit (or international members who are in the area), then you should really grab a copy of the exhibition book. It is really cool and informative, it's only €2,50 but 125 pages long (both in dutch & english) and it covers the evolution of whales, the ENCI whale, modern whales & their biology and about whaling and whales in human history & myth. The exhibition book alone is well worth the visit in my opinion, I kinda compare it with the EOS magazine about Iguanodons & the book "Mammoths: ice age giants by Adrian Lister" but then about whales. So here are the photo's I made of the exhibition. The Exhibition Room: left: Metepocetus sp. neurocranium with preserved ear bones from Liessel in the Netherlands (Miocene) Right: Isoluted vertebrae of various whale species from Liessel in the Netherlands (Miocene) Isolated vertebrae of Eocene primordial whales (Archaeoceti) dredged from the buttom of the North Sea, for comparison with those of the "ENCI whale" Isolated vertebrae of Eocene primordial whales (Archaeoceti) dredged from the buttom of the North Sea, for comparison with those of the "ENCI whale" Smallest jaw: possibly Dorudon sp. from the late Eocene of Ad Dakhla in Morocco. Bigger jaw: possibly Pappocetus lugardi, from the middle Eocene of Ben Gueran in Morocco.
