@Halichoeres : This is a great drawing of this ancient prehistoric tree and, it looks exactly like a ca. 4 metres high tree in front of my house!
The tree is now 40 years old, but I don´t know its scientific name!
The Araucaria nowadays is very old from prehistoric times, too, but looks totally different to your drawing, the neighbours opposite the street
have an Araucaria in their garden, it has very sharp leaves, is growing extremely slowly, but can get very old and tall!
Your drawings are absolut fabulous and I wished, I had so much talent to draw!
The drawing of Legnonotus is great, it looks very authentic and very real!
God bless you, to recover soon of your hurt!
To answer the question of
@Shonisaurus,the Araucarioxylon had a height up to 60 metres and 60 cm in diameter! Please,have a look into
Wikipedia and Google, there you´ll find a lot of articles about Araucarioxylon!
