Livyatan Vs Kentriodon - 'De grootste beet ooit', Rotterdam

Viendo la reconstrucción hecha por el paleoartista de una persecución del predador Livyatan melvillei a los Kentriodon uno entiende el porqué del título de la exposición en honor al cetáceo en Rotterdam: "De grootste beet ooit - La Boca Más Grande"!!!
Algo que es de notarse es que en esta reconstrucción se corrigió lo que pasó con el original en Lima: cuando recién montaron a éste los dientes estaban un tanto hacia afuera. Con este montaje posterior ya se arregló el asunto. Aunque quizás para muchos ojos haya pasado desapercibido el cambio.
Aunque no sepas holandés creo este video es ilustrativo:

  1. No, ni pizca de idea xD pero, le encuentro parecido al alemán.

    Sí, me acuerdo perfectamente del livyatan y su bocaza. Realmente increíbles esos tamaños. Se ve que la naturaleza era bruta entonces, aunqeu según cómo se mire, ahora sigue siendo bruta igual :)

    Un saludo :)

    Hi man,

    Livyatan looks like the largest and most powerful carnivore of all times ?

    1. I wouldn't be that sure about it, there's some debate concerning Megalodon as well. In addition the largest may not necessarily be the most powerful.

    You have an proper opinion about that ? Which had the largest jaws ?

    1. I read Livyatan may have had a more powerful bite, more fossils are yet to be discovered though

    And had it a larger jaw ? How many people could be engulfed in one bite ?
    Sounds like they say it has the biggest tetrapod bite known, but why they don't say in short the largest vertebrate bite ?

      hahaha!

      Yes, the title of the post says it all, the biggest bite as far as it is known.

    Impressive !
    But aren't megalodon jawe that size or larger ?

    1. Livyatan's skull is more than 3 meters large while Megalodon's is 2.5.
      Quite impressive nonetheless! isn't it?

  7. Hi Dinorider (it's ted here ;))

    Where did you get that megalodon's skull was 2,5 m ? I've not read such a data and the skull of sharks is particular, stockier and deeper than in a whale.

    Plus, the size of the skull is not the size of the jaws ;)

    1. I was told that by Aldo Benites, who works at the paleontology lab which worked on Livyatan's holotype.

    So, what was the size of megalodon mouth ?

    ResponderEliminar
  9. No one knows for sure but some rigorous reconstructions say the jaws were 3 m wide on the outside, 2 m wide on the inside and more than 2.50 m high.

    I don't remember the dimensions of the mouth of Liyatan, I guess it is huge but narrower and more elongated than megalodon.

    Hey thanks ! But why so liyatan had the more powerful bite ?

    ResponderEliminar
  11. We don't know if Livyatan had the most powerful bite, we have no measure for it and even for megalodon we are not certain despite there was a study about it.
    Sharks do not bite especially strong for their size, but megalodon was so large the bite may have been huge in life (numerous large whales bones are known slashed in two or with big gashes).

    Liyatan had certainly a monstrous bite force given the size of the jaws and the space for the maxillar muscles but we have no proper estimate figure at now. It is possible it rivaled or exceeded megalodon. However, bite force does not make obligatory the predator stronger itself...

    1. that's true Ted!

      studies on mechanics and stuff are needed! ... and more fossils as well!
