Right from the ceratopsians to the mammals!

MAKE WAY! A whole flock of ancient flyers are coming through! Here's the other piece I made for @fossil-fighters-zine !! I'm a lover of pterosaurs and had to rep EVERY SINGLE FLYER in the series.

April 15th is the Helicopter Day of Japan.The first practical helicopter was the Vought-Sikorsky VS-300,which first flew in the United States on September 14, 1939,but April 15th is actually the birthday of the famous painter and inventor Leonardo da Vinci,who drew the famous design sketch that is considered the prototype of the modern helicopter.However,people's exploration of the aerodynamics behind helicopters can be traced back to at least 1700 years ago.

The bamboo-copter is a ancient toy helicopter rotor from China,which is probably originated in Jin dynasty China around 320 AD.It consists of a shaft and propellers,and the shaft is rotated by friction between the palms of both hands,thereby generating lift for the propeller and making the toy fly into the air.In addition to being perhaps the first tangible device for what is generally understood as a helicopter top,the greatest contribution of bamboo-copter was that after it entered Europe,it inspired George Kelly and others to study modern aviation technology.That flying toy attracted George Cayley,the inventor of modern aeronautics,that made he began experimenting with helicopter tops in 1792,and copied and modified bamboo-copter in 1796.In 1835 Cayley remarked that while the original toy would rise no more than about 6 or 7.5 metres,his improved models would mount upward of 27 metres into the air.

Today, the modern form of the bamboo dragonfly is still used as a toy,especially in Asia that after Doraemon series has brought it back into popularity.

Although bamboo-copter inspired the theoretical basis of modern helicopters,there is no evidence or theory that it can carry humans into air on its own,at least from the past to the 21st century.

By the way,a Japanese science writer pointed out that the Hopter(Doraemon's bamboo helicopter) is either not powerful enough to carry people in flight or will cause harm to the user due to the reaction force.Later,the official explanation was that the hopter actually rises by anti-gravity,and the effect acts on the entire object,not just the contact surface between the hopter and the object.It's not so much to being a miracle of aerodynamics or propeller flight,it is more of a "failure" case.

here's some recent fossil fighters stuff ive done over the past several months

[henclair]

why don’t we talk abt the concept of raven and dexter being gay buds more often i literally think that’s they’re ideal dynamic

[captainmvf]

I feel like they designed Hopter just for me <3

hey guys

raptor-cock is a hupter pass it on
