Biologists have announced the discovery of the first-ever fossil specimens of flowering plants, possibly 15 million years old, that have been preserved in amber all this time.
The fossil “asterids ” are the antecedent to a staggering lineage of over 80,000 species, including the potato, tomatoes, tobacco, coffee, and the deadly poison strychnine.
In a paper published on Monday in Nature Plants , biologists explained that the flowery discovery was made in a Dominican Republic cave along with a treasure trove of insects, all preserved in amber. The discovery, dating back to 1986, yielded 500 fossils and led to decades of research on the fossilized insects, but little attention was paid to the flower until now.
I fossili "asterids" sono l'antecedente di una discendenza impressionante di oltre 80.000 specie, tra cui la patata, pomodoro, tabacco, caffè, e la velenosa stricnina mortale.
In un articolo pubblicato lunedi su "Nature Plants", i biologi hanno spiegato che la floreale scoperta è stata fatta in una grotta della Repubblica Dominicana, insieme a un tesoro di insetti, tutti conservati in ambra. La scoperta, che risale al 1986, ha rivelato 500 fossili e ha portato a decenni di ricerca sugli insetti fossilizzati, ma poca attenzione era stata dedicata al fiore fino ad ora.
