From the album: Fossil Amber and Copal: Worldwide Localities
La Toca Mine Cordillera Septentrional Santiago Province, Dominican Republic La Toca Fm. (Mamey Group) 20.43-13.65 Ma Specimen: 7.7g / 51x21x12mm Equipment: Samsung Galaxy S9 Plus BelOMO 10x Triplet Loupe Quantum 140lm LED Penlight The piece containing these inclusions is absolutely loaded with different arthropods, but the most spectacular inclusions are those of a swarm of 11 extinct Leptomyrmex ants: there are 9 complete and 2 incomplete individuals, averaging 3.5mm in body length. In a lighthearted interpretation, it appears as though the duo i© Kaegen Lau

A sizeable specimen originating from the La Toca Mine, Cordillera Septentrional, Santiago Province, Dominican Republic; specimen weighs 145.0g and measures 120x88x40mm. There are numerous visible flow lines, which are evidence of successive resin flows, each previous layer being slightly oxidized (discoloration): most of the layers in this piece are coated in small particulates. This piece is a transverse section of what was once a massive flow of resin-turned-amber, as evidenced by the raw outer "crust" with slight matrix on its three sides; the flow was likely formed as resin traveled downwa© Kaegen Lau

Small specimen of red-skinned blue amber from the La Toca Mine. Piece weighs 2.4g and measures 26x18x16mm. There are a few dendritic inclusions of moss, and as a whole, the piece is free of fractures and quite clean. The blue fluorescence is caused by certain hydrocarbons (i.e., perylene) that formed within the resin over its millions of years of burial; fluorescent hydrocarbons in amber are believed to be formed due to several possible factors: fire, geothermal or volcanic heat, prolonged submergence in a marine or lacustrine (lake) environment, etc. This specimen was partially polished and© Kaegen Lau

4.7g piece of amber from the La Cumbre Mine, measuring (mm) 25x22x15. It has a couple marcasite inclusions: seen here is a protruding portion (one half remains inside the piece) that was perhaps a gas bubble, but later infiltrated with iron and sulfur in solution during burial, migrating via a fracture/microfracture; or it may be a permineralized organic/inorganic inclusion (shell, quartz pebble, etc.), which are documented in amber from the La Cumbre deposit, and is called "double fossilization": while this occurs in tiny grains of younger La Cumbre amber which were deposited after the older© Kaegen Lau

Triple-phase inclusion and a few in-focus single and dual-phase inclusions nearby. The triple-phase bubble is a narrow chamber, possibly part of a methane termite (incomplete, heavily oxidized); there are two organic solids, the larger preventing the migration of the gas bubble. These inclusions are contained within the 5.4-4.7g specimen depicted in the four related photos.

Triple-phase inclusion (center right) and over twelve, viewable dual-phase inclusions nearby.

Opposing view of same specimen from associated image, weighing 10.0g and measuring (mm) 40x31x20; note the rough, unaltered (i.e., unbroken, natural) exterior of the specimen. Most dominican amber is transparent to translucent, yet this specimen is more akin in appearance to the "butterscotch" variety of Baltic amber; I have not determined if the turbidity is due to microscopic air bubbles, or organic inclusions, though it is most likely the former. This type of dominican amber is sometimes seen as a thin layer/flow overlying transparent material, but this specimen is mostly whole, and it's un© Kaegen Lau

Small run of amber from the La Cumbre Mine, weighing 2.4g, and measuring (mm) 37x13x8. It consists of numerous successive flows, and contains several small single-phase bubbles; as this specimen does, several others I have (from the same 2kg lot) from this locality also display an interesting "schiller" effect when adjusted in-hand (light reflects off of the flow lines' surface). Biological inclusions are a possibility with this specimen, though I will need to prepare it to confirm this.© Kaegen Lau

Dominican amber from the La Cumbre Mine, from the Cordillera Septentrional. Most pieces range from 5-10g in weight, with at least one containing a large two-phase inclusion (enhydro). Material from this mine frequently presents exterior crusts/aggregates of pyrite (iron sulfide); these were likely formed in a reducing, marine/lacustrine environment, where marine sediments, organic detritus, volcanic material (i.e., ash), and sulfate-reducing bacteria helped to provide the sulfides and iron needed.© Kaegen Lau

During March 6th to 13th I was in the Dominican Republic, and I found some fossils there. I was just organizing my collection yesterday and found these two “fossils?” That I never knew the ID of, i had my other fossils from the area ID, but not these two. There from Punta Cana, Dominican Republic. Thank you!

Hi I’m wondering if these are Tube Corals? I have a lot and found them in rocks and sand around my resort in Punta Cana, Dominican Republic, not to far from where I found my fossilized crab claw.

I have been on vacation for the past week and still am, at Punta Cana, Dominican Republic. I have found some pretty interesting specimens when walking on the beach or around the resort. Everything from a possible fossilized crab claw, fossil shells, cool minerals and possible fossilized plant roots, from the Quaternary period. Here is the area I found the fossils, and the fossils them selves!!

Hi in my post Varadero fossils By dinosaur man, December 29, 2019 in Questions & Answers i said that in February I will be going to Cuba. But since then plans have changed and March 6th I’m leaving to the Dominican Republic, Punta Cana. And i was wondering if there are any fossils that I would be able to find in that area, and if I can collect, or are the laws like Cuba too! Thank you!

Hello, My brothers friend recently found this beauty by a crop field in Bayaguana Dominican Republic (first and second picture). I believe it was found near water, a river of some sort. We can not figure out what it is, but while hunting the internet I came across the third picture which was posted on a tourist site and claimed to be found in Sosua Dominican Republic which is in the northern part of the island and by the ocean. Can anyone tell me what this could be, what could have made that shape?

Hi! I'm mostly here just because I'm interested in fossils haha, but I was wondering what this fossil might be? It's approx. 3-4 cm (pretty small!), and I also found it on the beach in Puerto Plata (Dominican Republic). This is more for curiosities sake, and just because I find them cool.
