DRAGONFLIES: ODONATA

Dragonflies, from the order Odonata, have been around for over 250 million years. The most conspicuous difference in their evolution over time is the steady shrinking of their wingspan from well over two and a half feet down to a few inches.

Voracious predators, today they dine on bees, wasps, butterflies and avoid the attentions of birds and wee lizards -- but back in the day, they had a much larger selection of meals within their grasp.

Time has turned the tables. Small lizards and birds who today choose dragonflies as a tasty snack used to be their preferred prey.

MOSQUE-CATHEDRAL, CORDOBA, SPAIN




















A mix of Muslim and Christian architecture can be found in the stunning, and oh so grand Mosque-Cathedral in Cordoba, southern Spain. Originally a small temple of Christian Visigoth origin, the Catholic Basilica of Saint Vincent of Lérins has an unusual and collaborative history. When Muslims conquered Spain in 711, the church was divided into Muslim and Christian halves.

This sharing arrangement lasted until 784, when the Christian half was purchased by the Emir 'Abd al-Rahman I, who then demolished the original structure to build the grand mosque of Córdoba on its ground.

Córdoba returned to Christian rule in 1236 during the Reconquista, and the building was converted to a Roman Catholic church, culminating in the inclusion of a Renaissance cathedral nave in the 16th century. If you are visiting Andalusia, it is well worth a day trip. Bring your camera and comfortable shoes.

OLD HABITS

Nuns stepping out from the palace, Cordoba, Spain




















A group of nuns stepping out in Cordoba, Spain. The nuns earn their living selling sweets and confections using recipes handed down from the Romans and Moors. Many convents are closing because they have fewer nuns so this art may one day be lost.

The procedure for buying the sweets is archaic, but charming. You enter the convent into a very small room with a lazy Susan installed on the wall.

While we did see some nuns in the street, many do not leave the cloister or appear in public. You never see the nun with whom you do the transaction, since these are cloistered nuns who avoid direct contact with the public.

On the wall beside the lazy Susan will be a price list. You look it over and decide which sweets you want to buy. Then you ring a buzzer on the wall. After a while you will hear the voice of a nun greet you and ask you what you want to purchase.

You tell her your order and after a few minutes the lazy Susan will turn and you will find your order on it. You then put your money on the lazy Susan and turn it so that the nun can get it. If there is change, the nun puts it on the lazy Susan and you then can get your change.

CARNOTAURUS SASTREI

Carnotaurus sastrei, a genus of large theropod dinosaur that roamed, Argentina, South America during the Late Cretaceous period, 72 to 69.9 million years ago.

This fellow (or at least his skull) is on display at the Natural History Museum in Madrid, Spain. For now, he is the only known genus of this species of bipedal predator.

The skull is quite unusual. Initially, it has a very marine reptile feel (but make no mistake this guy is clearly a terrestrial theropod). Once you look closer you see his bull-like horns (from whence he gets his name) that imply battle between rivals for the best meal, sexual partner and to be the one who leads the herd.

I'll be interested to see his cousins once more specimens of the genus are unearthed.
