Саблезубые тигры оказались сильнее, чем предполагалось ранее

Предназначение огромных клыков саблезубых тигров уже долгое время является причиной споров между разными учеными. Некоторые исследователи считают, что древние кошки убивали своих жертв только при помощи острых когтей, а клыки использовались только для протыкания их мягких шей. Другие же ученые уверены, что клыки были настолько прочными, что вполне могли пробивать кости — недавно у них появились весьма убедительные доказательства своей теории.

Саблезубые тигры оказались сильнее, чем предполагалось ранее

Недавно в научном журнале Comptes Rendus Palevol были опубликованы результаты исследования, в ходе которого на черепе саблезубого тигра были найдены проколы, предположительно сделанные зубами его сородича. Обнаруженные отверстия имеют круглую форму, и по диаметру соответствуют размерам клыков саблезубых тигров.

Клыки саблезубых тигров могли протыкать черепа

Это открытие раскрывает сразу два интересных факта о древних кошках. Во-первых, их клыки действительно могли быть крепкими и смертоносными орудиями, а во-вторых, они устраивали между собой сражения. Такое поведение можно заметить даже у современных хищников из семейства кошачьих, таких как леопарды, пумы, гепарды и пантеры.

Судя по найденным черепам, укусы саблезубых тигров не всегда были смертельными. На одном из образцов отверстие находится на верхней части носа, между глазами — на череп явно оказывалось большое давление, но обладатель явно пережил атаку.

Возможно, палеонтологи не правы

Между тем, некоторые исследователи относятся к новой теории с большим скептицизмом. По их словам, отверстия могли быть сделаны клыками других крупных хищников тех времен вроде огромных медведей. Также их могли оставить когти гигантских ленивцев мегатерий, или копыта другого животного.

Тем не менее форма и общие черты повреждений больше всего похожи именно на воздействие клыков саблезубых тигров. У исследователей есть еще одно подтверждение своей теории — найденные ранее окаменелости древних броненосцев показывали, что саблезубые кошки убивали их именно при помощи своих крепких клыков.

Для многих может оказаться большой новостью то, что окаменелый вид обретает только ничтожная часть костей древних животных. Чтобы стать окаменелостью, телам необходимы особенные условия, о которых можно почитать в нашем материале.

I truly enjoy reading your blog and I look forward to your new updates.

    First of all I would like to say terrific blog! I had a quick question which I’d like to ask if you don’t mind. I was interested to find out how you center yourself and clear your mind prior to writing. I have had difficulty clearing my thoughts in getting my thoughts out. I do enjoy writing however it just seems like the first 10 to 15 minutes are generally lost just trying to figure out how to begin. Any suggestions or tips? Thanks!

  15. security doors security doors 23.10.2020

    Write more, thats all I have to say. Literally, it seems as though you relied on the video to make your point. You definitely know what youre talking about, why waste your intelligence on just posting videos to your blog when you could be giving us something enlightening to read?

  16. Have you ever thought about creating an e-book or guest authoring on other blogs? I have a blog centered on the same subjects you discuss and would love to have you share some stories/information. I know my readers would appreciate your work. If you’re even remotely interested, feel free to shoot me an e mail.

  17. Superb blog! Do you have any tips and hints for aspiring writers? I’m hoping to start my own blog soon but I’m a little lost on everything.

  19. I was curious if you ever considered changing the layout of your website? Its very well written; I love what youve got to say. But maybe you could a little more in the way of content so people could connect with it better. Youve got an awful lot of text for only having 1 or 2 images. Maybe you could space it out better?

  20. Greetings! I’ve been following your weblog for some time now and finally got the bravery to go ahead and give you a shout out from Dallas Tx! Just wanted to mention keep up the great job!

  21. When I initially commented I clicked the «Notify me when new comments are added» checkbox and now each time a comment is added I get three e-mails with the same comment. Is there any way you can remove me from that service? Appreciate it!

  22. I’m not sure why but this site is loading extremely slow for me. Is anyone else having this issue or is it a issue on my end? I’ll check back later and see if the problem still exists.

  24. Howdy, i read your blog from time to time and i own a similar one and i was just curious if you get a lot of spam comments? If so how do you prevent it, any plugin or anything you can suggest? I get so much lately it’s driving me crazy so any assistance is very much appreciated.

  28. Have you ever thought about including a little bit more than just your articles? I mean, what you say is fundamental and all. However think of if you added some great graphics or videos to give your posts more, «pop»! Your content is excellent but with images and clips, this blog could certainly be one of the best in its field. Excellent blog!

  29. Hello! Do you know if they make any plugins to help with SEO? I’m trying to get my blog to rank for some targeted keywords but I’m not seeing very good gains. If you know of any please share. Cheers!

    Do you have a spam problem on this blog; I also am a blogger, and I was wanting to know your situation; many of us have created some nice methods and we are looking to exchange strategies with other folks, please shoot me an email if interested.

  31. Today, I went to the beach front with my children. I found a sea shell and gave it to my 4 year old daughter and said «You can hear the ocean if you put this to your ear.» She placed the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is completely off topic but I had to tell someone!

  34. Hi just wanted to give you a brief heads up and let you know a few of the images aren’t loading correctly. I’m not sure why but I think its a linking issue. I’ve tried it in two different web browsers and both show the same results.

  35. Hello! I know this is somewhat off topic but I was wondering which blog platform are you using for this website?

I would be awesome if you could point me in the direction of a good platform.

  36. I am really enjoying the theme/design of your web site. Do you ever run into any web browser compatibility issues? A small number of my blog visitors have complained about my blog not working correctly in Explorer but looks great in Safari. Do you have any ideas to help fix this issue?

  37. Hi! Quick question that’s completely off topic. Do you know how to make your site mobile friendly? My web site looks weird when browsing from my iphone4. I’m trying to find a theme or plugin that might be able to correct this issue. If you have any recommendations, please share. Thank you!

  42. I was curious if you ever thought of changing the page layout of your blog? Its very well written; I love what youve got to say.
