...DINOSAURS WALKED ON THE BEACHES IN LAGOS? lsobel Costa

THERE are dinosaur footprints on three beaches near Lagos. They were first discovered In 1995 on a fiat rock at the western end of Salema beach. Later, more prints were found Including at Porto de M6s and Santa beaches. These different sets belonged to an ornithopod and a theropod. Dinosaur tracks are known as trace fossils which are geological evidence of biological activity and can also Include feeding marks and burrows. The study of trace fossils is known as ichnology. Susceptible to erosion,

footprints are not always obvious but the ones at Salema and Santa can be seen after a small climb downsomecllffs. The Lagos Science Centre (Centro de Ci@ncla Viva de Lagos) organises for schools or private groups special twohour-long viewing trips to the beaches, whereby you can see for yourself the 125 millionyear-old footprints and learn all about the dinosaurs that roamed the Algarve. Antarctica Is the only continent In the world where dinosaur tracks have not been found but even so they

next to the tracks because bones and tracks fossilise at different rates, with bones fossilising when they have been buried quickly and prints fossilising over longer periods of time. Evidence In the Algarve Indicates that both herbivores and carnivores roamed the area and Portugal Is ranked seventh In recorded types of dinosaurs, 26 In all. Bones have been discovered here and along the coast from Sesimbra to Aveiro with the first discovered In 1863. Amazingly, some species are only known In Portugal

However, it was only in May 2014 that these were acknowledged as a new species of long-necked herbivore which was subsequently named 2by Atlantlcus, in

predator ever discovered in Europe, as well as one of the largest carnivorous dinosaurs that lived over 150 million years ago. Identified as Torvosaurus gurney!, this dinosaur with 10-centimetre long bladeshaped teeth was probably at the top of the food chain.lt grew to 10 metres in length and weighed up to five tons,

lt has around 23,000 inhabitants, 12kms of coastline and is home to the Lourinh3 museum, founded in 1984, which has the largest Iberian collection of dinosaur fossils and one of the most significant worldwide. I visited the museum a few years ago and was fascinated by the displays of full skeletons, fossil collections

Portuguese professions and a full size cottage, all showing tools and furnishings from the early 20"' century. lt was one of the best museums I have ever visited. Dinosaurs have always intrigued us and who is not in awe when visiting exhibitions with the wonderfully realistic full-scale robotic models around today. The

Algarve, why not take your children to visit the science centre in Lagos? lt is "a place where science, fun and hands-on learning are practice d all year round". Everyone will enjoy participating in the indoor and outdoor Interactive activities which are based on discoveries Involving 'Orientation and Navigation',

Find out what it is like to row a boat, tie sailors' knots, build a lighthouse and experiment with maps and prisms and see some of the plant species brought back from the original Caravela trips. Open daily (lOam to 6pm), except for Mondays, the centre Is well worth a visit. Of course, you can also book to see the dinosaur tracks as not many people can say they have seen real dinosaur footprints on the beach! So now you know ...
