A lot of people have commented that they would like to see a semiaquatic system, as well as more semiaquatic species, get added in Jurassic World Evolution 3. I personally think it is a good idea as it would help make the game more realistic and offer a wider array of species that lived in different environmental conditions. Some suggestions I have for how to create a semiaquatic enclosure include:
-Alter the terrain tools to allow us to use fresh water or salt water
-Alter the terrain tools to allow us to be able to control the depth of the water
-Add a vegetation brush for Mangrove trees (that can only be used in or near shallow water)
-Give terrestrial species swimming animations, excluding the smaller ones that avoid deep water
-Add Decompression sickness (DCS, aka the bends) as an illness and drowning as a cause of death
-For aquarium enclosures, add the ability to create a beach, sandspit, and or tombolo along the edge of one part of the aquarium
-For aquarium enclosures, give players the ability to control whether the aquarium is salt water or fresh water
-For aquarium enclosures, allow players to control the aquariums depth and attach parts of it to terrestrial enclosures so certain semiaquatic species, like Spinosaurus, can use it (similar to how the Zoo Tycoon games did it)
For semiaquatic species, I would recommend:
Paracyclotosaurus, An extinct genus of temnospondyl amphibian that lived during middle Triassic period, about 235 million years ago, and fossils have been found in Australia, India, and South Africa. It grew to be around 2.45 meters (8.0 ft.) long and weighing between 159 and 365 kg (351 and 805 lb.). It is known from a single specimen that was discovered by quarry miners in a brick pit in St. Peters in Sydney, New South Wales, Australia. The discovery, made in 1910, was from a large ironstone nodule within Ashfield Shale which contained the nearly complete skeleton. The Genus name means Near Wheeled Lizard. The Species name is a reference to Sir Tannatt William Edgeworth David, the individual who arranged for the British Museum (Natural History) to acquire the specimen.
Cyclotosaurus, An extinct genus of temnospondyl amphibian, that was part of the Mastodonsauridae family, that lived during the mid to late Triassic period and was found in Greenland, Germany, Poland, and Thailand. It was of great size for an amphibian. It represents the last of the Mastodonsaurids. Its name means "round eared lizard" in Ancient Greek, derived from round openings or fenestrae in the cheeks, which are thought to contain structures of the middle ear.
Koolasuchus, An extinct genus of brachyopoid temnospondyl in the family Chigutisauridae. Fossils have been found from Victoria, Australia and date back 125-120 million years during the Early Cretaceous. It grew to be around 3 meters (9.8 ft) in length and weighing up to 500 kilograms (1,100 lbs.). Koolasuchus is the youngest known temnospondyl. It is known from several fragments of the skull and other bones such as vertebrae, ribs, and pectoral elements. K. cleelandi was adopted as the fossil emblem for the state of Victoria, Australia on 13 January 2022.
Arenaerpeton, An extinct genus of chigutisaurid temnospondyl found in the Terrigal Formation of New South Wales, Australia. It is estimated to have grown around 1.2 meters (3.9 ft); the surviving section of the holotype measures around 94 centimeters (37 in) long. The genus name is derived from the Latin "Arena", meaning "sand" (a reference to the sandstone block in which the holotype was found); and "erpeton" meaning thing that creeps (commonly used in fossil amphibians). The species name "supinatus" means "supine", referring to the fact that the fossil is lying on its back.
Aphaneramma, An extinct genus of marine temnospondyl amphibian that lived during the early Triassic period, approximately 240 million years ago. Fossils have been found in the Mianwali Formation of Pakistan, Madagascar, the Zhitkov Formation of Russia, and the Kongressfjellet Formation of Svalbard (Norway). It grew to be around 2 meters (6.56 feet) long. It had jaws similar to the gharial, which has led researchers to suggest that it primarily hunted fish. (I got the length by looking at the Italian version of the article using Google translate.)
Dinocephalosaurus, a genus of long necked, aquatic protorosaur that inhabited the Triassic seas of China. It is thought to be a marine species based on poorly-ossified and paddle-like limbs which would have prevented it from going ashore. One specimen discovered at the Luoping locality preserves a embryo within its abdomen, indicating that Dinocephalosaurus gave birth to live young like many other marine reptiles. Dinocephalosaurus is the only known member of the Archosauromorpha to give live birth, with the possible exception of the metriorhynchids, a group of marine crocodylomorphs. It was a large member of the Protorosauria, attaining a maximum body length of at least 3.5 m (11 ft). Its name is derived from the Latin words din- ("terrible"), cephalo- ("head"), and saur ("lizard") to create the genus name Dinocephalosaurus, which refers to the "ghastful skull" of the holotype.
Augustaburiania, An extinct genus of tanystropheid archosauromorph from the latest early Triassic period from the Volgograd Region, western Russia. All specimens were recovered in the right slope of the Don River valley from the Lipovskaya Formation. Augustaburiania is the oldest known tanystropheid.
Tanystropheus, An extinct genus of archosauromorph reptile which lived during the Triassic Period in Europe, Asia, and North America. Tanystropheus is one of the most well-described non-archosauriform archosauromorphs, known from numerous fossils, including nearly complete skeletons. Some species within the genus may have reached a total length of 6 meters (20 ft), making Tanystropheus the longest non-archosauriform archosauromorph as well. Its genus name means long hinged.
Qianosuchus, An extinct genus of aquatic poposauroid archosaur from the middle Triassic Guanling Formation of Pan County, China. It is represented by two nearly complete skeletons and a crushed skull preserved in the limestone. Qianosuchus grew to be around 3 meters long. It had several skeletal adaptations which indicate that it had a semi-marine lifestyle, similar to modern-day saltwater crocodiles. These adaptations have not been seen in any other archosaur from the Triassic.
Liaoningosaurus, An unusual genus of basal ankylosaurid dinosaur from the Liaoning Province, China that lived during the early Cretaceous period in what is now the Yixian and Jiufotang Formation. It is the oldest ankylosaurid to have had a tail club. The largest specimen grew to be around 45 centimeters (1 ft 5 in) long. It has been speculated by some experts that it may have hunted or scavenged, based on the preserved gut contents showing that it may have eaten fish and may have been semi-aquatic, but this has been heavily debated. I do think if they add it to the game the developers should make it so this species requires a lot of water in its enclosure and maybe require it to have a fish feeder in its enclosure.
Halszkaraptor, a genus of waterfowl-like dromaeosaurid dinosaurs from Mongolia that lived during the Late Cretaceous period. The holotype specimens remains were compared to bones from extant crocodilians and aquatic birds, and found evidence of a semiaquatic lifestyle; although this is being debated. It is believed to have specialized in hunting aquatic prey. The generic name combines a reference to the late Polish paleontologist Halszka Osmólska, who was involved in many expeditions to Mongolia and named the closely related Hulsanpes, with Latin raptor, "robber". The specific name honours Escuillié for having made the specimen available to science.
Natovenator, a genus of halszkaraptorine dromaeosaurid dinosaur from the Late Cretaceous Barun Goyot Formation of Mongolia. It is regarded as being an efficient swimming dromaeosaurid with a semiaquatic lifestyle. The multiple convergences with other aquatic vertebrates include an elongated snout with numerous teeth, delayed replacement pattern of premaxillary teeth, a complex neurovascular system on the snout tip, elongated neck and vertebral zygapophyses, and a retracted, long naris (nostril opening). The generic name, "Natovenator", is derived from the Latin words "nato", meaning "to swim", and "venator", meaning "hunter", in reference to its piscivorous diet and possible swimming behaviour. The specific name, "polydontus", is derived from the Greek words "polys", meaning "many", and "odous", meaning "tooth".
Chupkaornis, A genus of prehistoric flightless birds from the Late Cretaceous (Coniacian-Santonian) Kashima Formation of Hokkaido, Japan. It is the best-preserved hesperornithiform material from Asia and it is the first report of hesperornithiforms from the eastern margin of the Eurasian continent. The genus name was made from the combination of the Ainu word ‘chupka’, meaning ‘eastern’, and the Greek ‘ornis’ for bird.
Baptornis, A genus of flightless, aquatic birds from the Late Cretaceous, some 87-80 million years ago found in Kansas and Sweden. At the time it was alive time, Kansas was mostly covered by the Western Interior Seaway, a shallow shelf sea. Othniel Charles Marsh discovered the first fossils of this bird in the 1870s. This was, alongside the Archaeopteryx, one of the first Mesozoic birds to become known to science.
Hesperornis, A genus of cormorant-like Ornithuran found in present day Canada, US, and Russia that lived during the Late Cretaceous period. It grew to be around 1.8 meters (5.9 ft.) in length. It had virtually no wings, and swam with its powerful hind legs. Hesperornis primarily lived in marine habitats. However, some of the youngest known specimens of Hesperornis have been found in inland freshwater deposits of the Foremost Formation, suggesting that some species of Hesperornis may have eventually moved, at least partially, away from a primarily marine habitat. Its name means western bird. It was featured in Prehistoric Planet.
Canadaga, A flightless bird genus from the Late Cretaceous, about 67 million years ago. It lived in the shallow seas around what today is Bylot and Devon Islands in Nunavut, Canada. It is one of the largest known members of the Hesperornithes, reaching a length of 2.2 meters (7.2 ft.). It also represents one of the last known members of the lineage. Unlike its relatives which are mainly known from subtropical or tropical waters, this species seems to have ranged in temperate or even subarctic areas.
Thalattosaurus, An extinct genus of marine reptile from the late Triassic period in the family Thalattosauroidea found in the Sulphur Mountain Formation of British Columbia and the Upper Triassic Hosselkus Limestone of California. It has gained notoriety as a result of studies on general diapsid phylogeny. They were aquatic diapsids that are known exclusively from the Triassic period. It was a 2–3 metres (6.6–9.8 ft) long shellfish-eating reptile with paddle-like limbs and a down-turned rostrum. Its name means sea lizard.
Askeptosaurus, An extinct genus of askeptosauroidfound in Middle Triassic marine strata in what is now Italy and Switzerland. It grew up up to 2.5 meters (8.2 feet). It is known from several disarticulated and articulated skeletons. These specimens were discovered in the Grenzbitumenzone of Monte San Giorgio, a UNESCO World Heritage Site on the Swiss-Italian border. Also known as the Besano Formation in Italy, the Grenzbitumenzone has produced many well-preserved fossils from the Anisian-Ladinian boundary.
Miodentosaurus, A genus of thalattosaurian (a type of extinct marine reptile) from the Late Triassic of China. It is one of several thalattosaurs found in the Xiaowa Formation, also known as the Wayao Member of the Falang Formation. It grew around 4.4 meters (14 ft.) long. It is one of largest known thalattosaurs. The genus name "Miodentosaurus" translates to "Few toothed-lizard" while the species name "brevis" means "short", in reference to its short snout.
Hibbertopterus, A genus of eurypterid, a group of extinct marine arthropods. Fossils of Hibbertopterus have been discovered in deposits ranging from the Devonian period in Belgium, Scotland and the United States to the Carboniferous period in Scotland, Ireland, the Czech Republic and South Africa. Hibbertopterus was the largest eurypterid within the stylonurine suborder, with the largest fossil specimens suggesting that H. scouleri could reach lengths around 180–200 centimetres (5.9–6.6 ft). Hibbertopterus is likely to have been the heaviest Eurypterid due to its broad and compact body. The type species, H. scouleri, was first named as a species of the significantly different Eurypterus by Samuel Hibbert in 1836. The generic name Hibbertopterus, coined more than a century later, combines his name and the Greek word πτερόν (pteron) meaning "wing". Though long hypothesized, the fact that eurypterids were capable of terrestrial locomotion was definitely proven through the discovery of a fossil trackway made by Hibbertopterus in Scotland. The trackway showed that an animal measuring around 160 centimeters (5.2 ft) had slowly lumbered across a stretch of land, dragging its telson (the posteriormost division of its body) across the ground after it.
Mixopterus, A genus of eurypterid, an extinct group of aquatic arthropods from Late Silurian age found in Europe and North America. The largest species, M. simonsoni, reached lengths of 75 cm (2.45 feet). The structure of the tail of indicates that Mixopterus would be able to move on land, but such movement would likely be difficult because of its weight. Respiration would not be an issue, since moist gills would be well concealed above the ventral plates. Mixopterus might have buried itself in the sand to wait for prey, as the swimming legs were very well-adapted for digging.
