Colorful scales
Amber bear on ancient brute with a level of point unrivaled by specimens fossilized in rock . By scrutinizing a group of lizards entrap in amber 99 million age ago , scientists discovered a routine of unusual feature article that helped them key out the lizards ' billet on their phratry tree . This look-alike shows the scale on a preserved hind leg with scale leaf pigmentation still visible , at 7X enlargement .

Toe the line
A toe on the isolated , preserved hind stage of a Cretaceous lounge lizard , at 4X blowup . The amber also hold a layer of backbone texture with slime mold cling to them , designate that the lounge lizard had been combat-ready on sandy ground .
Say “aaaah”
Soft tissue paper seldom survive in fossils preserved in rock , but amber can protect delicate social system , keeping them intact for millions of years . This lizard ’s protrude tongue is seeable as a gray blob near the top of the frame , at 5X overstatement .
Putting his best foot forward
The left-hand forefoot of a lizard that was preserved as a hollow body pit , surrounded by a clear , scaley epidermis .
“There are things more horrible than death”
Long , lank toe on the right foreleg of this specimen prompt the researchers to nickname it " Nosferatu , " after the long - fingered vampire from the 1922 silent flick by F. W. Murnau .
The lovely bones
cypher X - ray imaging ( CT ) scan allow scientists to build 3D digital models of the trapped lizards . Amber preserved the skeleton of this gecko - like lounge lizard , particularly its skull , mandible , 26 vertebrae and pelvic bones . The flabby tissues either decayed or were scavenge before rosin completely cover the skeleton .
Imprints in amber’s “memory”
Even if the lounge lizard ' bones were n’t maintain , sometimes they left " atmosphere bubbles " behind in the amber that held their former contour . scientist used these to cast of characters models of internal anatomical structure , like this tooth row .
On the tip of his tongue
In this specimen , scientist observed epidermis with some coloration , the skeleton and some organs — the tongue , for example — that were mostly intact .
