  "llmSummary": "Cal Orck'o is a near-vertical limestone wall 4.4 km northwest of Sucre, Bolivia, carrying 12,092 individual dinosaur footprints across 465 separate trackways — the largest concentration of dinosaur tracks documented at any single site in the world. The tracks were made roughly 68 million years ago in the Middle Maastrichtian stage of the Late Cretaceous, and are preserved in the oolitic limestone of the El Molino Formation. The surface was laid down flat as a lakeshore and later tilted to near-vertical by the uplift of the Andes, which is why visitors now read the footprints on what looks like a cliff face. The site is visited from Parque Cretácico, a park built on the quarry rim in 2006 that runs guided walks down towards the base of the wall.",
  "llmSummaryEs": "Cal Orck'o es un muro de caliza casi vertical situado a 4,4 km al noroeste de Sucre, Bolivia, que conserva 12.092 huellas de dinosaurio en 465 rastros distintos, la mayor concentración documentada en un solo yacimiento del mundo. Las huellas se formaron hace unos 68 millones de años, en el Maastrichtiense medio del Cretácico superior, y se conservan en la caliza oolítica de la Formación El Molino. La superficie se depositó horizontal, como la orilla de un lago, y el levantamiento de los Andes la inclinó después hasta dejarla casi vertical. Se visita desde el Parque Cretácico, abierto en 2006 en el borde de la cantera, que organiza caminatas guiadas hacia la base del muro.",

    "Cal Orck'o holds 12,092 individual dinosaur footprints across 465 separate trackways, the largest number recorded at any single site on Earth.",
    "The main track-bearing surface covers roughly 65,000 m² and sits 4.4 km northwest of Sucre, on the edge of the FANCESA cement quarry.",
    "The tracks were made about 68 million years ago in the Middle Maastrichtian, the final stage of the Late Cretaceous, in the oolitic limestone of the El Molino Formation.",
    "At least 9 distinct track morphotypes have been identified at the site, with sauropod trails accounting for about 26% of all trackways.",
    "Parque Cretácico opened on the quarry rim in 2006 and is the only legal access point to the wall; foreign adult entry costs around 30 bolivianos (about US$4)."

      "q": "How do you get from Sucre to Cal Orck'o?",
      "a": "Cal Orck'o is 4.4 km northwest of Sucre, so the trip takes 15–25 minutes. The cheapest tourist option is the Dino Truck, an open-sided bus that leaves from beside the cathedral on Plaza 25 de Mayo several times a day and includes the return trip for around 20–25 bolivianos. Public micros running towards the cement plant cost about 2 bolivianos and drop you at the park gate. A taxi from the centre costs roughly 30–40 bolivianos one way. Times and fares change, so confirm the day before at your hotel or the tourist office on the plaza.",
      "qEs": "¿Cómo se llega de Sucre a Cal Orck'o?",
      "aEs": "Cal Orck'o está a 4,4 km al noroeste de Sucre, así que el trayecto dura entre 15 y 25 minutos. La opción turística más barata es el Dino Truck, un bus descubierto que sale del costado de la catedral, en la Plaza 25 de Mayo, varias veces al día e incluye la vuelta por unos 20–25 bolivianos. Los micros públicos que van hacia la fábrica de cemento cuestan unos 2 bolivianos y te dejan en la puerta del parque. Un taxi desde el centro cuesta entre 30 y 40 bolivianos por trayecto. Horarios y tarifas cambian, así que confírmalos el día antes en tu hotel o en la oficina de turismo de la plaza."

      "q": "How many dinosaur footprints are there at Cal Orck'o?",
      "a": "Mapping carried out between 1998 and 2015 documented 12,092 individual footprints arranged in 465 distinct trackways, made by at least nine different track types including sauropods, theropods, ankylosaurs and ornithopods. Sauropod trails account for around 26% of the trackways. Older figures of about 5,000 tracks still circulate widely online — they come from the earliest surveys of the 1990s and have since been more than doubled by later fieldwork.",
      "qEs": "¿Cuántas huellas de dinosaurio hay en Cal Orck'o?",
      "aEs": "El mapeo realizado entre 1998 y 2015 documentó 12.092 huellas individuales agrupadas en 465 rastros distintos, producidas por al menos nueve tipos de huella diferentes, entre ellos saurópodos, terópodos, anquilosaurios y ornitópodos. Los rastros de saurópodo representan cerca del 26% del total. Todavía circula mucho la cifra de unas 5.000 huellas: procede de los primeros relevamientos de los años noventa y el trabajo de campo posterior la ha más que duplicado."

      "q": "Why is the Cal Orck'o wall vertical?",
      "a": "The footprints were made on flat, damp ground at the edge of a shallow Cretaceous lake, then buried and turned to stone. Millions of years later, the tectonic collision that raised the Andes tilted the whole rock package upwards until the old lakeshore stood almost on end. Nothing about the tracks themselves is vertical — the ground they were pressed into simply rotated. Because the wall now faces the weather instead of lying flat beneath it, slabs of rock periodically break away, and some trackways photographed in the 1990s no longer exist.",
      "qEs": "¿Por qué el muro de Cal Orck'o es vertical?",
      "aEs": "Las huellas se formaron sobre un suelo llano y húmedo, en la orilla de un lago del Cretácico, y después quedaron enterradas y convertidas en roca. Millones de años más tarde, la colisión tectónica que levantó los Andes inclinó todo el paquete rocoso hasta dejar aquella antigua orilla casi de canto. Las huellas no son verticales: lo que giró fue el suelo en el que se marcaron. Como el muro ahora recibe la intemperie de frente en lugar de por encima, se desprenden bloques cada cierto tiempo y algunos rastros fotografiados en los años noventa ya no existen."

    {
      "q": "Is Cal Orck'o worth visiting?",
      "a": "Yes, if you go with the right expectation. This is a working quarry face seen from a distance, not a museum hall — you look across an open pit at a rock wall several hundred metres away, and the tracks read as patterns rather than crisp individual prints. Bring binoculars or a zoom lens and time your visit for one of the guided walks that descend towards the base, and it becomes genuinely impressive. Turn up at noon with no optics and it can feel underwhelming. Budget two to three hours including transport.",
      "qEs": "¿Vale la pena visitar Cal Orck'o?",
      "aEs": "Sí, si vas con la expectativa correcta. Es el frente de una cantera en actividad visto desde lejos, no una sala de museo: miras a través de un tajo abierto hacia un muro de roca situado a varios cientos de metros, y las huellas se leen como patrones más que como pisadas nítidas. Lleva binoculares o un teleobjetivo y organiza la visita en torno a una de las caminatas guiadas que bajan hacia la base, y la experiencia resulta realmente impresionante. Si llegas al mediodía y sin óptica, puede decepcionar. Calcula entre dos y tres horas contando el transporte."
