سلام دوستاي خوبم. يه مقاله جالب درباره دايناسورها ديدم که گفتم براي شما هم بزارم تا بخونيد. اگر هم به مبحث دايناسورها علاقه منديد براي اطلاعات بيشتر مي تونيد به خود وبسايت هاي مرجع Dino Dinosaur و dino Dinosaurs مراجعه کنيد.





بياييد سفري به گذشته هاي بسيار دور داشته باشيم و با خطرناک ترين جانوراني که تاکنون در کره زمين زندگي کرده اند آشنا شويم. در واقع اين يک موهبت بزرگ است که اين جاندارن امروز منقرض شده اند چراکه در غيراينصورت زندگي انسان در کره زمين غيرممکن بود. در اين مقاله به معرفي خطرناک ترين دايناسورها مي پردازيم، و شايد اينکه آنها هرگز به زندگي دوباره در کره زمين برنخواهند گشت را مي توان خبر خوبي قلمداد کرد!
