Something that is extinct.
yes Dr.Shancy found the first fosils and put it in a museum which is now destroyed
Who knows?Not me but ask the sinitist they found the foosils and foot prints.
(EXAMPLE)Casts of flora and fauna are created by (for example) a leaf falling into mud millions of years ago. the mud eventually hardens forming sandstone and therefore, the leaf is embedded within this. bones, twigs, small animals like mice or fish are commonly found in this way. After pressure from surface material or the build up of further sand or mud, whole bodies can become trapped, leaving complete skeleton fossils. Ice is another good producer of foosils or petrified casts, like mammoths, Sabre tooth tigers etc.
