Viumbe Donasari!

[Mbao za Mawe]

Nimesoma kwa juu habari ya hawa viumbe kwenye Ukurasa wa habari wa BBC SWAHILI (FACEBOOK) ila nimetaka kukua kwa undani viumbe hawa ambao inasemekana walikuwepo miaka takribani milioni 200 iliyopita.

Kwa mwenye kufahamu hawa Viumbe naomba anizibue ufahamu niwajue hata kidogo.

Dinasour
Nguva
Aliens
Popo bawa

Wametungwa wote

Kiumbe kimekufa million 200 iliyopita wanavyodai lakini wanatuchorea mchoro wa dinasour alivyokuwa ,umbile lake lote .

Wanatuonyesha Aina za dinasours na wamewa categorize kwa makundi mbali mbali

Aina ya chakula walizokuwa wanakula

Idadi ya mayai waliyokuwa wanataga na life style yao kiujumla

Yaani kiumbe kimeondoka ulimwenguni 200million iliyopita wanavyodai walijuaje hayo yote kama siyo kutufunga kamba?.

dinosour ni uongo hakujawahi kuwa na wadudu kama hawa duniani,hawa wana-exist kwenye science fiction tu na huko ndiko walikobatizwa na kuwa science fact. kama mambo mengi tunayoamini kuwa ni ukweli huanza kwenye fiction hadithi ikishakolea na kujaa akilini mwa watu hugeuzwa kuwa fact, hakuna proof yeyote badala ya video za kutengeneza na photoshop na mifupa ya kughushi. pengine superman na spiderman watakuja kua fact baada 200 years
ni muendelezo wa uzushi tunaoaminishwa ili tuamini kuwa evolution ni ukweli na alien wapo pia.ili tuone the past ilikuwa ugly kwa hio na future pia inaweza kuwa ugly hii ni kuiweka akili katika mazingira ya woga kwenye maisha yote ya mwanadamu na tuamini kuwa mwanadamu hakuumbwa bali wanatufundisha tuamini na evolution

na kama hii ni kweli mabaki yao yangeonekana na watu wa kawaida tu lakini kila yanapoonekana yanaonakana na wanaotafuta wa mifupa hio na sio watu wa kawaida kama wakulima na wachimbaji na wajenzi,na pia yangeonekana kila pahala na zaidi hapa africa na sio hizo sehemu wanazosema wanayaona,evidence zote wanazoleta ni za kughushi,mifupa mabufuru ya vichwa kila kitu ni vya kutengeza

A Brief History of Dinosaurs

Most people think of dinosaurs as big, ferocious and extinct reptiles. That's largely true, but there are some misconceptions. Dinosaurs came in all shapes and sizes. Dinosaurs were the largest land animals of all time, but a great number of dinosaurs were smaller than a turkey.
Dinosaurs first appeared between 247 and 240 million years ago. They ruled the Earth for about 175 million years until an extinction event 65.5 million years ago wiped out all of them, expect for the avian dinosaurs. Scientists don't agree entirely on what happened, but the extinction likely was a double or triple whammy involving an asteroid impact, choking chemicals from erupting volcanoes, climate change and possibly other factors.


Flying on
Only the big, classic dinosaurs are extinct. Birds are living dinosaurs, most experts believe. Think of that next time a pigeon strafes you.
Fossils show that some of the more advanced dinosaurs had feathers or feather-like body covering, but many of them didn't fly and probably didn't even glide. Archaeopteryx, which was for a long time considered to be the first bird (although this status is not certain), could likely launch itself from the ground, but probably couldn't fly far, according to unpublished research presented at the 2016 Society of Vertebrate Paleontology meeting in Salt Lake City, Utah. Instead, feathers, likely helped these bird-like dinosaurs stay warm as juveniles or send signals to other individuals.
Many people think extinct flying reptiles called pterosaurs were dinosaurs. They were dinosaurs' closest relatives, but technically not dinosaurs. Pterosaurs had hollow bones, relatively large brains and eyes, and, of course, the flaps of skin extending along their arms, which were attached to the digits on their front hands. The family includes
Pterodactyls , with elaborate, bony head crests and lack of teeth. Pterosaurs survived up until the mass die-off 65 million years ago, when they were went the way of the dodo along with marine reptiles and other nonavian dinosaurs.


Hip check
Dinosaur fossils were first recognized in the 19th century. In 1842, paleontologist Richard Owen coined the term dinosaur, derived from the Greek deinos , meaning "terrible" or "fearfully great," and sauros, meaning "lizard" or reptile." Scientists classify dinosaurs into two orders — Saurischians and Ornithischians— based on the structure of the bones in their hips. (This saurischian and ornithischian grouping is now disputed. See the "Family tree update" section below to learn more.)
Most of the well-known dinosaurs — including Tyrannosaurus rex ,
Deinonychus and Velociraptor — fall into the order known as Saurischian dinosaurs (pronounced sor-ISK-ee-en). These "reptile-hipped" dinosaurs have a pelvis that points forward, similar to more primitive animals. They are often long-necked, have large and sharp teeth, long second fingers, and a first finger that points strongly away from the rest of the fingers.
Saurischians are divided into two groups – four legged herbivores called sauropods and two-legged carnivores called theropods (living birds are in the theropod lineage).
Theropods walked on two legs and were carnivorous. "Theropod" means "beast-footed" and they are some of the fearsome and most recognizable dinosaurs — including Allosaurus andT. rex .
Scientists have wondered whether large theropods — such as
Giganotosaurus and Spinosaurus — actively hunted their prey, or simply scavenged carcasses. The evidence points to the animals working together as opportunistic hunters: they would bring down prey, but also eat animals that were lying around. When fossil-hunters found bones with bite marks on them, they wondered if theropods engaged in cannibalism. It appears now that the animals may have scavenged their own kind, but they didn't hunt down their own.
Sauropods were herbivores with long heads, long necks and long tails. They were among the largest land animals ever, but they likely had small brains. The gentle giants like leaf-eating Apatosaurus , Brachiosaurus and Diplodocus are part of this family.

Ornithischia
Ornithischian (pronounced or-neh-THISK-ee-en) dinosaurs, a group that includes horned and frilled
Triceratops, spiked Stegosaurus and armored Ankylosaurus , are more mild-mannered, plant eaters.
These dinosaurs were beaked herbivores. Smaller than the sauropods, the ornithischia (meaning "bird-hipped") often lived in herds and were prey to the larger species of dinosaurs. Interestingly, the ornithischia shifted from a two-legged to a four-legged posture at least three times in their evolutionary history and scientists think they could adopt both postures early in their evolutionary history.

Family tree update
In 2017, a metaphorical bombshell hit the paleontology world regarding the dinosaur family tree. A study published in the journal Nature suggested that this hip-oriented classification was incorrect. Rather, theropods are likely close cousins with the ornithischian dinosaurs, and the two groups — the theropods and Ornithischia — form a newly identified group known as Ornithoscelida, the researchers said.

The finding came about after researchers realized that theropods and Ornithischia had many anatomical features in common . If the updated tree is correct, it may explain why both theropods and Ornithischia have feathers, while other dinosaurs don't.
However, this hypothesis will need to be tested and retested over the next several years before the paleontology community can fully accept it.

Marine reptiles
During the age of the dinosaurs, a lot was happening below the surface of the world's oceans. The "fish flippers," or ichthyopterygia, includes Ichthyosaurus — the streamlined, tuna- and dolphin-shaped ocean-going predators. This abundant family of marine reptiles largely went extinct at the end of the Jurassic Period.
Dinosaur cloning
Despite the popularity of the "Jurassic Park" franchise, it would be incredibly difficult, if not impossible, to clone a dinosaur. In order to clone a dinosaur, researchers would need dinosaur DNA. But there is no known surviving dinosaur DNA on record (the oldest recovered and authenticated DNA sample belongs to a 700,000-year-old horse that lived in ancient Canada.)
However, some dinosaur organic matter has withstood the test of time. Researchers have uncovered a number of soft tissues from the Mesozoic era, including 80-million-year-old blood vessel belonging to a duck-billed dinosaur and 130-million-year-old proteins in an early bird fossil. But blood vessels and proteins, unlike DNA, cannot be used to clone animals.
There is a concerted effort to reverse engineer a chicken into a dinosaur (remember, birds are the descendants of theropod dinosaurs), but the team still has a ways to go.

Ona sasa ulivyo danganywa na wew bila kufikiria unaanza kusadiki ili ukadanganye wenzio tangu lini mnyama akataga mayai?

Kwa mujibu wa wanasayansi waliojikita kwa dinosaurs wamesema dinasours walikuwa wanataga na ilikuwa inachukuwa muda mrefu kwa mayai kutotoa

Mbona hushangai mamba ,Kobe kutaga

Dinosaur kama reptile wengine yeye alikuwa anataga kama vile nyoka ,mamba nk
