LA GUERRA DE LOS HUESOS

¡Cómo me gustan las historias de la #historia de la #ciencia!

Os dejo una de las más notables de la #paleontología, la que a finales del s. XIX protagonizaron dos buscadores que andaban a la greña por ese #fósil de más.

Para #HilosDC8 de @Sci_Granada👇!
1- En concreto hablamos de los norteamericanos Edward #Cope y Othniel #Marsh.

My hair's getting long, but not long enough to tie into a ponytail, which is my intention in this time when we avoid barbers. You can see how long my hair has become in the selfie I posted today. In it I sit at my desk...
...working on my laptop, my immense desk towering over me and clutter filling the space that is not filled by electronics. I chose black and white for this composition as I do for all my best selfies. It's unique because...
...I show myself from the back, a trick I mastered by resorting to the ten second timer in one of my cameras. I don't know how I feel about this photo -- perhaps you have something to say. I'd be very interested.
