From today's featured articleAmbondro mahabo is a mammal from the middle Jurassic (about 167 million years ago) of Madagascar. The only species of the genus Ambondro, it is known from a fragmentary lower jaw with three teeth (pictured), interpreted as the last premolar and the first two molars. The premolar consists of a central cusp with one or two smaller cusps and a cingulum (shelf) on the inner, or lingual, side of the tooth. The molars have a similar cingulum, three cusps at the front, and a talonid with a main cusp, a smaller cusp, and a crest at the back. Features of the talonid suggest that Ambondro had tribosphenic molars, the basic arrangement of molar features also present in marsupial and placental mammals. It is the oldest known mammal with putatively tribosphenic teeth; at the time of its discovery it antedated the second oldest example by about 25 million years. (Full article...)

Today's featured picture
Cardinal Richelieu (9 September 1585 – 4 December 1642) was a French clergyman and statesman. He was consecrated as a bishop in 1607 and was appointed foreign secretary in 1616. Richelieu soon rose in both the Catholic Church and the French government, becoming a cardinal in 1622 and King Louis XIII's chief minister in 1624. He remained in office until his death in 1642; he was succeeded by Cardinal Mazarin, whose career he had fostered. This picture is an oil-on-canvas painting by French artist Philippe de Champaigne, entitled Triple Portrait of Cardinal de Richelieu, completed c. 1642. The portrait shows the cardinal from three angles: right profile, face-on, and left profile. Aged nearly 60, he wears a scarlet liturgical skullcap (zucchetto) and cape (mozzetta). Under the broad collar of a white shirt, tied at the neck with a trailing string, is the characteristic blue ribbon of the Order of the Holy Spirit, from which hangs the Maltese cross of the order as a pectoral cross. The painting is now in the collection of the National Gallery, London. Painting credit: Philippe de Champaigne
