Leptolepis (from Greek: λεπτός leptós, 'slight' and Greek: λεπίς lepis 'scale') is an extinct genus of stem-teleost fish that lived in what is now Europe (Germany, Luxembourg, France, England, Italy and maybe Greece) and North of Africa (Algeria, Tunisia and Morocco) during the Jurassic period (Pliensbachian–Callovian ages).
